I stayed at the apartment for one month. The pluses are its location (easy walking distance to all the major sights and to the Arno river), and the other tenants are all lovely. The room is a good size, with plenty of storage space and a pleasant view. It has its own ensuite wet-room bathroom. The landlord’s agent was very nice and helpful, and gave me tips on local amenities, etc.
On the down side, when I stayed there (Feb-Mar 2018) the apartment needed a lot of work done to it. The major issues were that the boiler could not cope with the low water pressure, so I had to put up with a lot of cold showers, or no shower at all, because the water would just stop mid-flow. The oven in the kitchen did not work, which I asked to be repaired (it wasn’t). The creaky old bed in my room was just horrible. It has a slope, which I found quite disconcerting! I think that this place desperately needs some TLC!
