Besides the fairly small, not to easy to find alley, the fairly preoccupied and unprepared staffing meeting us, the fain smell of sewage in the lounge and breakfast area (which might come from the rivers), the obvious poorly and cheap renovations (eg. Very bad plastering, terrible painting work, and the very ugly, cheap, poorly laid and already laminate that were laid in the entire hotel), which also probably leads to the faint smell of mold on the room (and the poorly installed door to the bathroom that scraped the floor all the way, not ensuring propper ventilation in the bathroom), the not too good beds, the broken fridge, the moisture damage on the flooring, doors and windows and very expensive breakfast (that we did not try due to its price); the hotel were actually OK.
We were fortunate enough to get a room with balcony where we could was all the Gondoloes pass by, which was actually quite cosy to enjoy a glass of wine with. It was quiet and had functional air-conditioning and the bed was at least clean.
However, the best way to describe Hotel Tiepolo:
Just a place to sleep, fairly unconfortable, for a tad bit cheaper than a propper hotel.
Dont stay here. Do yourself a favor and find a 10% more expensive hotel that actually give proper service and don't have the obvious aura of "We refurbished a hotel as cheaply as possible and now just make it run, just to make money".
