Nai provided excellent instructions (including photos) on how to get to his apartment and how to enter the building and the apartment. He was very helpful and reliable. His studio is in an excellent location on a charming quite street, near many sights and cafes etc. The bathroom is quite small but may be typical for such a location. The building is 400 years old so people shouldn't expect the halls and stairwells to look as bright and unworn as a modern hotel. Overall we were quite content.
