Maddalena's flat was great. Our flight into Rome was delayed and she waited at the apartment to give us a guided tour and orientation of the flat. She is truly an incredible host and knows what she is doing. She had a nice welcome note with emergency contact information, taxi numbers, Wifi username and password, the address, metro stop information, and a mini TV guide. I cannot say enough nice things about the bathroom - it was clean, she provides mini "hotel-like" soaps, and actually had a bathmat for us (the only host to do so in our four city tour of Europe). The only negative aspect (and it's purely our opinion and subjective) was the humidity and lack of air conditioning. It was about 80°F (~25-30°C) during our stay in late May to early June and the flat got warm. She had a nice cooling fan that we used at night to try and stay cool. Also, I was a little nervous to rent an apartment on the first/ground level but I want future guests to know that there is a locked gate at the street and then another one to get into the building.
Bottomline: good location, very responsive host, clean apartment, basic amenities above and beyond, and I would stay here again if visiting Rome.
