We stayed for 3 nights in the beginning of July and had a very nice stay! The apartment location is truly excellent - it's quite walkable from the central train station, the historical center and river with beautiful bridges, a lot of restaurants and cafes are within a few steps, and there's even a supermarket on the same street where you can get everything you might need.
The apartment itself is very interesting because of the stairs and it feels very authentic, with multiple design elements (like wall decoration or wooden doors) kept from the ancient times. The wooden floor is a true pleasure for feet and the bed is comfortable.
The weather was extremely hot and we had to change clothes every day, but as we had only hand luggage, the washing machine in the apartment as well as iron were truly useful items!
However, due to central location and wooden windows of the apartment which we couldn't close completely because the air conditioning unit is window unit, not the built-in, the noise from the street can be heard and for me it was disturbing during the night, when there were loud companies walking by from time to time. Main purpose of my visit to Florence was trade fair, so I was in a need of a good sleep and it was a bit irritating to wake up often because of the noise, but on the second night I got used to it and this is quite normal for such a location in proximity of main tourist routes.
Marialaura has been very attentive and responsive throughout our communication - the check-in was easy and smooth, with good recommendations on places to visit.
Thank you very much! ;)
