Staying at Gio's place is a great experience. The location puts you in a cozy neighborhood a brisk 10-minute walk from the train station. Although we only met for a few minutes at check-in, you can tell Gio has a wonderful personality. Warm and funny, he's a thoughtful host who welcomes you into his very personal space. He only asked that we "respect the house" and we had a great 3 days in Florence thanks in part to living in his 600 year old apartment.
The room is super spacious and even the loft was comfortable for me to stand fully straight in (1.85m /6'1). The bed was medium firm and the comforter perfectly warm.
The neighborhood has a laundry and a local market with everything you'd need to cook a meal. A good variety of cafés and restaurants are also within 5 minutes walking distance.
