Just perfect. The apartment was clean & tidy, very homely and had everything we needed. Beautiful balcony, perfect for an afternoon glass of wine. Dish washer, clothes washer, stove, fridge, etc. Everything we needed was there. Also had air conditioning and two boys screen LCD TVs.
The location is amazing. About 15 mins walk to the Vatican and there's a Metro Station less than a minute's walk away.
Lots of great restaurants and cafes in the area and Valentina was kind enough to leave details of some recommended restaurants. Also several grocery stores in the area (search for "Coop" if you're having trouble finding one) which makes it a great place to bring back some ingredients for a mezze platter if you don't feel like dining out.
Lots of towels were provided and there at two bathrooms which are both perfect. Big showers, looking very new and very clean.
Valentina's father met us on arrival as we flew in very late & were delayed on the flight. Such a nice guy, very hospitible and explained everything very well to us, even giving information about some of the attractions, good areas, etc in Rome and pointing them all out on a map for us.
All in all, a perfect stay in an amazing apartment in a fantastic location.
Will definitely be staying there again the next time we're in Rome!
