We stayed at Jacopo's apartment for 4 days in a very cold week in January. The apartment is a lovely, well designed and newly renovated place on the second floor of very steep stairs. Jacopo welcomed us and helped with the luggage. He was very helpful and responsive, provided us with loads of tips with regards to the neighborhood restaurants and sights. The apartment was absolutely perfect , the heating system was a blessing. For the summer are air condition units in every room.
Location could not be better, Oltrano is within 5 minutes walk from the Ponte Vechio but out of the hustle and bustle of the historic center.
I hope to come back soon!
