Mario received us and was extremely kind and helpful. He explained every single detail about the apartment and checked via messages if everything was ok every once in a while. As mentioned in the description, the apartment is in the third floor of a quite old building, so the stairs can be a problem if you have heavy bags. Luckily, you usually only go up the stairs with your luggage once per stay! The apartment had a washer and dryer that worked perfectly and was a huge help! Although Mario has left instructions (with pictures!) about regulating the hot water in one of the bathrooms, we had some problems with that. The other shower, on the other hand, was excellent! Wifi was strong and fast! The location was good and bad, actually. It's really close to the train station, so we were able to get there in about 5 minutes after getting off the train. It is a short walk to the main attractions of Florence, too. However, we were not comfortable with some groups of dodgy looking men who stood in the corners of the street all day, "doing nothing", kinda watching over something. Please let me be very clear here: We were not harassed or threatened by these men in any moment. In fact, they barely looked at us. We just did not feel comfortable at all in that environment. We even avoided going out at night because of this. But that was just a perception, nothing happened while we were there. Also, as mentioned before in other reviews, people talk quite loud down at the street until late hours. This is not the host's fault and there is nothing he can do about it, but I believe it should be mentioned. We have nothing but good things to say about Mario.
