It is really a convenient place to stay during our visit in Roma, it’s also quiet and cozy. The only problem is the building is quite old, so when the first time I try to unlock the door I met lots of problem, but it was successfully resolved. Marie is very patient! Little tips for using the key: When using the smaller key to open the downstairs door, lift the key as far up as possible so that it clicks into the catch. When using the larger key to open the door above, twist it harder to the right.
