My boyfriend and i stayed for one night with Yeh. Marta was out of town at the time. He was very helpful and kind. We were exhausted from backpacking in the heat and it was nice to be welcomed. the location as perfect. down the street from ponte vecchio and real close to the Duomo. although there was No Air Conditioning, Yeh did his best to supply us with a fan to keep us cool.. it wasn't much but we did manage to get a good nights sleep. we would definitely recommend Marta & Yeh to friends but would make them aware of the heat/airconditioning.
