We stayed at Barbara’s place for two weeks and it was wonderful! Perfect apartment for my husband and I. It’s about a 20 minute walk to the train station and centrally located near the duomo and all the museums. We knew ahead of time that it is on the 4th floor with no lift- she has it listed on her description. It’s a hike up but we did fine (and used it as our excuse to be able to eat more gelato!) Barbara was very helpful!
