Nice, clean, comfortable, with a very chic, contemporary room design. The design aspect almost made up for the extremely small size of the room (small for folks used to American-sized hotel rooms). A very nice bonus feature was the free mini-bar in the room, though I only used it for the bottled water in it. Internet connectivity is available both wired (which I used) and through WiFi (which I didn't), and is free. There are plenty of electrical outlets for all the modern travelers' accessories that need charging.
The booking.com description said that "private parking was available on- site", and this is incorrect: the hotel has no parking facilities of its own at all, and all nearby Frankfurt city parking lots close for entry by 9:00 pm every night. The only alternative, if you return late at night, is to park on the street (if you are lucky to find such parking).
Located in Frankfurt (Gutleutviertel), Hotel Europa Style is within a 15-minute walk of Frankfurt Opera House and Staedel Museum. Featured amenities include dry cleaning/laundry services, a 24-hour front desk, and luggage storage.
Policies vary by room type and provider.
