We were a family of 6 on vacation in Florence. Our first impressions of Ilaria's apartment were great - the location is truly unbeatable, as you are right in the center of it all, and the apartment is lovely! We were met on arrival, given a tour, and were sent some recommendations for local restaurants and shops - which were wonderful! Check-in was easy and communication was great.
The real complaint we had was regarding the hot water. First, although there are two bathrooms, we were told that we could not use them at the same time - for a group of 6 you can imagine this was a bit inconvenient, but OK, we made do. However, getting hot water was really a gamble. There are cords in the showers that you must pull to get the hot water to flow, and the heat only lasts for a short time, so you have to constantly pull it. And they didn't work at all at night, for some reason, and only some mornings! Cold showers are not my thing. Furthermore, whenever the cord was pulled, it set off a buzzer that could be heard throughout the flat - heaven forbid you try to take a shower while other people are sleeping.
If the hot water situation is fixed, the apartment would be a truly great place to stay and we would highly recommend it.
