We were 4 adults and we stayed at the 2 room apartment. The place is within walking distance to all shopping areas, taxi stand and tour bus stop were right outside. The Master's Bedroom was very spacious and had the perfect view of Duomo. Other than those, there was not much positives about the place.
1) There was an elevator going up to the apartment but you still had to climb a flight of 8-10steps before the elevator. Being a group of 4 ladies with luggages , the flight up before the elevator was a big inconvenience.
2) The description online can sleep 4: there was 1 king bed but the other 2 beds were awkwardly set up inside the kitchen. So you can't really rest well when you're sleeping in the common area.
3) Only 1 had the proper amenities of a shower. The other only had a tub, without curtains. If you want to use it as a shower you need to hold up the shower head yourself.
4) The sheets were clean but not the apartment. Floors and windows were dusty. Rugs were old and stained, so was the sofa. Kitchen amenities were also not clean.
5) The host had us wait 30mins upon check in for reason we never knew. We weren't oriented on the different amenities: ie high tech tub, wifi, TV
