We stayed at Alessia's place in late November. The apartment is well located, on Piazza Navona. The view from the patio is wonderful! We really enjoyed sitting out, people watching and taking in Bernini's fountain. The 3 bedroom and 2 bath space worked very well for our group, which included my wife and I in one room, my mom in the second and my sister in the third. Almost everything in the city center is within a 15-20 minute walk at most. Lots and lots of bars and restaurants around, and a couple of bus stops just outside the apartment that will get you mostly anywhere you want to go (though Roman buses are kind of a crapshoot on timing). There is some noise from the Piazza, including what I think is a daily early-morning garbage and recycling truck. But I think the tradeoff of having the patio overlooking the Piazza was well worth it!
