We had a great time. Max organized the airport transfer for us. Once we arrived, he greeted us with a very delicious apple pie, a bottle of wine and water. He explained everything about the flat and the surroundings. Furthermore, he is very quick to respond to any requests and questions and does everything to accommodate your every wish.
The flat is exactly as described and is equipped with everything you could possibly need. It is very close to grocery stores; the Vatican is within walking distance. There is also a metro station close by that takes you to all the other attractions.
I highly recommend you stay with Max!
