The apartment is fine, however, it opens directly onto the main street - there is a 'private entrance' as described but the door is locked and you do not have access to it. Additionally, there are not bars on the glass entry door - the host assured us everything was fine and that it was perfectly safe - but this is something you should know before booking. The stairs up to the bedroom are very, very steep and the walk from the main station is a good 30 minutes.
Nicoletta was a very communicative host and easy to get in touch with. The A/C was great and the apartment was clean and very functional and easy to reach from most of the main attractions in the city. Also, there was no glass window in the bathroom, just a wooden door that did not seal fully and left the bathroom very humid/noisy from the outside.
