Lufthansa Senator Club First Class Lounge

Excellent airport lounge for a layover in the Frankfurt airport. If you are Start Alliance gold be sure to check it out. You’ll probably need it just as a place to catch your breath after walking through the ever-​sprawling airport (seriously, the place is ridiculously huge, can take 30 min to walk to a connecting gate!)
Lounge is large with comfy chairs (nice variety between couches, tables, and overstuffed chairs.
Food was alright — sufficient but not superb. Lowlight of the lounge IMO but still decent. While food selection wasn’t the largest, there was a very sufficiently stocked bar to make up for it.
Showers — definitely the best part. Really nice individual shower rooms with everything you need and probably have packed away in your checked baggage (towels, toiletries, blow drier, etc). Was really nice to get off a red eye (that had been delayed by 3 hours) and be able to freshen up during the 2 hour layover.
Only thing that I would have really liked to have seen was water bottles — they only had large glass bottles and cups, nothing to take with you to the plane.
Will definitely be back next time I fly through Frankfurt.

Great place to get a shower, decompress and freshen up before your meeting or decompress mid-​way on your journey.
I often take a flight with a short layover in FRA so that I can take a shower instead of go on a 18hr direct flight to the other side of the world.

Stylisch, neu eingerichtet. Getränke und Buffet-​Auswahl in Ordnung. Nichts besonderes, keine Überraschungen … LH-​typisch.

Die neue Non-​Schengen B Senator Lounge ist eine der schönsten Loungen Europas. Lufthansa hat sich hier viel Mühe gemacht, den Gästen mit modernem Design und Komfort das Warten etwas angenehmer zu machen.
Die Lounge beinhaltet wunderschön gestaltete private Duschen, die wie ein teures Spa gestaltet sind. Nach Anmeldung kann man hier in Ruhe duschen.
An der Bar gibt es schmackhafte Cocktails, die vom Barkeeper frisch gemixt werden!
Leider legt Lufthansa bei den angebotenen Speisen nicht viel Wert auf Qualität. So gibt es eigentlich täglich das gleiche — Würstel mit Senf oder belegte Brote mit immer denselben Quark-​Aufstrichen.
WLAN ist für alle Lounge-​Besucher kostenlos.

This review is actually for their First Class Terminal (yes, Terminal, not a tiny lounge).
LH has First Class Terminal at Frankfurt — you can use if you fly LH First or have their HON status. They have their own immigration officer, duty-​free store, cigar lounge, restaurant, bar (yes, you can get Johnny Walker Blue Label, too), spa (bath & shower), nap rooms, individual mini offices, etc. within the building. It is located 5 min walk away from the main terminal. They used to provide limousine ride from the main terminal, but they stopped the service recently.
Once you walk in to the terminal, one of the personal concierges greets and takes your passport (to be handed over to the immigration officer). Then, you will go through X-​ray and screening process, but unlike regular areas it’s very relaxed and friendly atmosphere as they only have 3 or 4 passengers at a time. No long queue, no screaming, no pressure from an obnoxious guy behind you, etc. After that, you can check the duty-​free store, enjoy full-​service restaurant, bar, nap, shower, bath, cigar… until your concierge comes and escorts you downstairs for boarding.
At the restaurant section, you can select items from the buffet counter, or order individual dishes from servers. They serve various meals based on the time (breakfast, lunch, supper, snack).
One of the coolest features is that they give you a ride in a fancy car — either Porsche or Mercedes to your plane. Once you get to your flight’s gate, your driver takes you to the elevator which will take you right on to the boarding area, then you will be introduced to the flight purser/​manager.

This was my first opportunity to have enough time to fully use the First Class lounge at Frankfurt International Airport, and I enjoyed every minute of my layover today in this lounge. Compared to the domestic first class lounges in the USA, this Lufthansa lounge is top tier because of it’s wide range of amenities and things to eat/​drink.
Complimentary full food buffet with fresh breads, sandwich making platters, yogurt with fresh cut pineapple and a complimentary Full Bar with high-​end liquors. Full cheese bar, several nut/​snack choices, two levels of hard-​boiled egg doneness, six different fresh-​squeezed juice choices, a rainbow of granola/​energy bar choices, four different Keurig-​type coffee/​tea machines, complimentary T-​1 speed WiFi, 150 baseball-​leather lounge seats each with 2 power outlets each, HDTVs, and my FAVORITE: Eight spa-​quality 130sf private shower rooms with rainshowers and sideshowers, toilet, teak changing bench with 4 fresh bath towels, and a fully stocked sink vanity with hairdryer, toiletries, shampoo and conditioner. When you sign up for a shower, they give you a pager to let you know when your shower room is clean and ready. There is also a salon on the shower wing of the Lounge. My room was ready faster than I could finish my breakfast.
This is some serious perkage that will inspire even the casual traveler to consider putting all of their frequent flying eggs in one airline basket. It’s not just about getting a great seat (or bed) on the plane. There’s way more to it, and this is just one of many awesome benefits of airline loyalty. Go Star Alliance!
