I'm echoing what most reviewers here are saying. I stayed here for a week during Carnevale and it was a great experience. The owner and brother and staff all very nice and friendly and made me feel comfortable (though I didn't have any real questions other than location of one place on a map).
This is from perspective of a single traveler, and I look for the following: central location, safe surroundings and hotel, cleanliness very important, and nice shower with real water pressure. This hotel has all that. Very clean and tidy room; good water pressure in shower which is important to me. Also, free wifi works great. I had a room w/bath one night (because the owner was nice enough to offer to me at same price as room w/shared bath since it was available), and with shared bath rest of the time. Both are on higher floors (3 or 4?). One room faced street and other faced next building. Frankly I had no problem with noise even with street facing room -- and during Carnevale, perhaps bc it's a bit higher up. A little music from some bar nearby till about midnight and that's it, and maybe some late night revelers now and then. The windows are very thick.
Yes, the rooms I had are on the small side. But as a single traveler that was fine for me. It may be a problem if you're a couple with lots of baggage and/or not used to being in really close quarters. And you need to lug your luggage up the smallish stairs -- the site makes that very clear. Honestly not a big deal to do it twice (and walking up a few flights every day is probably good given all the good food we're eating there). So know yourself before booking. But for this price it's a fantastic value. Highly recommend.
