This is a lovely little place to stay in for a couple of days. We were welcomed with a bottle of red wine and cold bottled water, fully equipped kitchen, two sets of towels and tiny schampoo. If you are an active tourist and you just need a place to sleep - I would consider this place luxurious. The studio is actually a part of a larger apartment, but has been split apart so it could be rented. The neighbor has a dog which barks rarely.
The best part is the location. You couldn't be more central than that. Everything is in walking distance. The host has kindly provided a tour map of sights as well as a list of recommend places to eat - fantastic list. Please try them. Just around the corner from the building's entrance is the best foccocia place called All'Antico Vinaio - that one is not on the list, but ver yhard to miss.
Enjoy your time here!
