This is a wonderful apartment. It feels "real" yet you don't feel like you are intruding on someone's daily life. Dorotea is cheerful and helpful. The location could hardly be better. It is near everything in the center yet is tucked away to the side so it feels private. Everything worked, which is special for Rome. The furnishings are comfortable and attractive with a feel for the past.
BE AWARE: There is no air conditioning. They don't claim to have it. This is probably not a problem for 90% of the year but it is a bit rough when it is 90 degrees and humid. They have many fans but it does not really draw.
Also, the stairs are very steep and tiny and the elevator is very old and small. This was not a problem for me but I would know that if you are at all unstable it could be an issue.
But truly a wonderful apartment at a fair price!
