This is a lovely apartment and staying here made our three days in Rome very special. Firstly, everything that needs to work was in perfect working order, the elevator, the air conditioning, the hot water and the wifi were all faultless. The place is spotlessly clean and bright, well equipped, spacious and stylish. It is brilliantly placed! It is close to everything - we walked everywhere, including the Vatican, (which may not have been such a great idea on such a hot day, but when it is less than 35 degrees Celsius, it is perfectly do-able). It is very close to the Piazza Venezia and the huge Victor Emmanuel Monument, so we always had a landmark to head for, which is very useful. The bathroom is huge and the apartment is very quiet, although the entrance is off a main road, the apartment faces onto a quiet street and we were never disturbed by street noise.
Secondly, Maria and Francesco were super helpful. Maria arranged an airport transfer for us, which is very helpful when arriving in a foreign city off an overnight flight, and Francesco met us at the door and helped us to settle in. He answered all our subsequent questions promptly via Whatsapp and he made us feel very welcome.
We were a party of two adults and two teenagers and we felt the apartment was more than big enough for us all. It could easily sleep six if two of the occupants are children.
I highly recommend this apartment.
