The flat is in a very convenient location in the heart of the city, on a narrow side street. While little is on your street, good restaurants and a bakery are just a couple blocks away. The Uffizi gallery is just 5 minutes away and most other sites and the train station are 10 minutes. The cute kitchen had the basics for cooking, but the food outside was so good we decided not to cook for ourselves. The flat has clearly been remodeled nicely in just the last couple of years.
We did have three complaints about the flat: 1) as others have commented, it has very little natural light, especially in the bedroom, as the flat is basically shaped like an "L" with the only real window at the top and the bedroom down around the corner. Wake up on a sunny day and you'd never know it. 2) the water had a peculiar taste and smell, like burning rubber. At first we didn't mind it but we ended up switching to bottled water. 3) the wireless Internet was very unreliable, especially in the bedroom. We often experienced no data being received even with full bars of wifi. We didn't bring any of these to our host's attention, so we don't hold it too strongly against them, but because of these they don't earn 5 stars.
Overall, while this flat was a good value, we would choose to stay somewhere a bit brighter.
