I wouldn't recommend this establishment.

Liked: Location was fine, not far from city center.
Disliked: Cleanliness was not appropriate. First we arrived found bugs on our bed (didn't make attention, but found that guests have already noted such problem). Cleanliness of the bathroom - very bad smell of a toilet or a cat's toilet (don't know). Ventilation in the room was dirty, when I opened and checked it (photo is below)We asked to check towels - 2/3 towels were not clean. You have to pay for slippers - 6 euros , hotel doesn't give them for free, what is a normal service. Parking - 25eur per night, near the hotel parking is for free, and many vacant places.Breakfast - costs 23eur per person, if you book 1 day before they offer it for 19eur. Quality of breakfast honestly should be 10eur.

Superb

Liked: Friendly, helpful staff, great price, ok location but not much close by. Overall very happy, thanks.

very disappointing experience

Liked: Just the tram stop was right outside the hotel
Disliked: The room was ok, the water kettle didnt work , after several attempts it didnt heat up the water. Then i was served hot water in a jar. No body replaced the water kettle after talking to the reception about it. While showering the soap bottle was empty , i didnt realized that was over and wasn't there (no shampoo / conditioner in the bottle) i was standing in the shower for 10 minutes soaked wet till they sent someone with soap/shampoo etc.. very very disappointing. There was some constant noise around, the breakfast was ok not what i expected. i am not staying here if i happen to be in Frankfurt.

Pleasant

It was above my expectation....

Liked: Location excellent for Frankfurt Messe by tram.The staff were professional, very, very helpful and always with a lovely smile. Thank you.
Disliked: I would have liked two choices of sweets for breakfast. I didn't enjoy the jam doughnuts.

Very good

Exceptional

Disappointing Stay

Liked: Not much.
Disliked: The hotel's overall management does not meet expectations of the international traveller's: (1) when we checked in the room was not cleaned and as a result we had to ask a room change, (2) shower gel/shampoo bottles were empty and had to run down to reception desk for a refill (for both rooms we stayed), (3) rooms are not cleaned unless you make a make-up room request , claiming eco-friendly policies, and (4) only one bottle of welcome water is provided on the day of arrival and for additional bottles 7.5 Euros charge is applied for a small bottle of water (500 cc), (5) 19 Euro breakfast at the restaurant is disappointing.Overall a very disappointing stay for me and my friends for 3 nights.

Good stay

Liked: We got an upgrade so we were happy, since we stayed for 3 nights.
Disliked: Parking in the hotel is extremely expensive. Lucky that we always found a spot along the street
