Guido's apartment is located in the heart of historical Florence, so location-wise it's perfect although the only way to reach is via taxi or by walk (not suggested if you've got luggage like we did.) The lift was very helpful. We had a problem with hot water during our stay that couldn't get fixed immediately but Guido accomodated us with his private bathroom, he lives next door. The doors are a bit thin so privacy-wise and for light sleepers I would say it's not the best. But for 2 nights it's great. The kitchen and washing machine appeared to be helpful too!
