The apartment is beautiful (just as in the pics but even bigger than we thought!). It's very clean and equipped with: two towels per person, a hairdryer, several dishes, some basic food stuffs (like condiments), extra bedding, an iron and pretty much anything else you might need.
Most importantly, it's in the perfect location - v. central but on the south side of the river, with fewer tourists around. It's about two minutes walk (if that) to Pitti - one of the main attractions in Florence, and a few minutes to Ponte Veccho.
It's also 30 seconds away from a very lively square where mostly locals eat and drink.
David was very welcoming. He not only gave us maps on which he marked the best restaurants (all super close to the apartment) and attractions. He also left us a delicious bottle of wine made by his friend!
Highly recommend!
