The little studio is just as described. It is perfectly located and you‘re in the Vatican City within minutes, the rest of the major attractions are reachable within a 30 minute walk! The check in was super easy Annamaria is super helpful and showed me a few of her favourite places/recommendations on a map.
Yes the shower cabin is small, but it‘s enough to take a proper shower and I did not have any problems! The house is really quiet and since the windows are towards the inner courtyard, you can even leave them open at night.
