Anastasia's apartment was even better than we expected. The bedrooms were spacious.Mattresses luxurious. The terraces lovely - and a rare treat for Rome. Two lovely bathrooms and underfloor heating, dishwasher etc - even slippers and shopping bags provided for all the guests. The apartment was so clean you could eat off the surfaces. Anastasia thought of every comfort for her guests and was always very responsive if we needed anything, offering to book restaurants, taxis etc.
Around the apartment: Having lived and travelled in Italy I can guarantee 'I Fratelli' about 50m from the flat will be the best pizza you have in Rome. Start with a Margherite to get a true taste of the classic Neapolitan pizza. Directly opposite the flat is a Pastificio (and actual Pasta Academy) with a big glass window where you can watch fresh pasta being made and you can buy either to cook yourself or to take away (ready prepared). 50m in the other direction is a great Ice cream place called Gelato Paoletti. Also opposite the flat is a park and playground with really cool eco-carousel made out of recycled stuff and powered by bike. There is a pharmacy at the end fo the road and there are 3 supermarkets very close to the flat, one of which 5 min walk away is a Carrefour which is open 24/7.
About the area: Google street view can give you an idea of the area. Don't be put off by graffiti, very common in Rome. This is a residential/university area so quite relaxed. You have a 10 minute walk to the nearest metro through some areas near the back of the station. Not the nicest streets but we never felt unsafe and the underpass under the tracks is a well used pedestrian route so again we felt safe. You might not want to walk around the back of the station very late at night but it's pretty busy most of the time. 5 Minute walk to the tram which goes to the Colosseum/Forum etc. and bus stops to centre Spanish steps etc right by apartment.
We visited in February so a bit cold to use the terraces and often dark by the time we got home. Nevertheless the kids favourite thing about their visit to Rome was the 'Apartment' .. and hiding in the spacious wardrobes. :-)
