My experience in La Casina di San Zenobi was great!
Despite arriving later than what my boyfriend and I planned, Edoardo and his mom kindly waited for us, letting us checking in without any issue.
The place is extremely close to the heart of Florence (5\10 minutes walk from the main attractions and museums) and there's plenty of restaurants around. Not far from the apartment a few supermarkets and pharmacies are available as well.
About the apartment: La Casina di San Zenobi is a small one room apartment that has really everything you need. It's nicely furnished, organized and above all, it was spotless clean.
The bed is super comfortable and the bathroom despite being small is well kept and functional.
The only downside I would point out is the kitchen, as cooking on the electric stove they put to use isn't exactly practical, but that is understandably the only thing possible they could have installed.
Other than that, everything else has been 100% worth the price.
I would definitely recommend Edoardo and his Casina to all my fellow travelers who are in search of a comfortable and nice place to stay while exploring the city!
