This apartment could not have been any better. The location is amazing- so close to Piazza Della Signori but virtually no noise from the street. Loads of great restaurant choices close by and no more than a 5 minute walk from all main sites in the centre.
The apartment itself is very comfortable- especially the beds!- and well appointed. Alessandro and his wife were perfect hosts, sending a video of all of the things we needed to know (wifi!, fuse box location, how locks worked, air-con/heating). These things normally take a day to work out when all you have is a visitors book/guide. We were met on arrival and after another very quick tour (all of the main detail was in the video) they left us with some recommendations of lots of restaurants for the next 2 days.
All in all, it's hard to suggest anything that could have been better. We had a brilliant time. Highly recommended.
