Guido is a great host! He responded to our requests very quickly and he is very attentive. He greeted us on the first day and the arrangement was great. The location of the apartment was great, it was within a walk-able distance from Santa Maria Novelle train station (around 20 minutes-walk, though we cabbed it from the train station on the first day). The apartment was lovely, it was located on the third floor of an old building. It was very clean and tidy, it had everything we needed. The location was also very convenient as it was central to all the main attractions with shops, restaurants and museums nearby. Although the street could be a bit noisy at night (possibly from people walking home from bars etc.), but it was generally a very quiet and very safe neighbourhood. Highly recommend!
