There was a Sports Gambling parlour & Ladies' Spa & Tanning salon on bldg ground floor (photo)- those places looked sleazy.
The Apart sign at location read Apart Hotel "Boarding House" (photo). A Boardinghouse suggests a different type of clientele than a guest hotel. Do not recall online listing as Boardinghouse, only Hotel when I booked it. Getting to Apart was very hard to find & drive car to. Parking was ? and area was poorly lighted, sketchy, and dirty looking (photo). Apart Boardinghouse entrance was NOWHERE to be found, despite searching on foot. This was just as well. Taken as a whole, we did not feel safe, so we got the heck out of there!
Stayed instead at a beautiful full service Hilton in Mainz that was fabulous! Had 2 terrific rooms with river view at this Hilton for less than the cost of 1 room at (ugh) Apart Boarding House. We do not recommend this property for families or really anyone else. Good luck (and consider yourself warned) if you still choose to stay at The Apart Hotel Boardinghouse in Wiesbaden.
