Very conveniently located apartment:
1. Taxi station is right next to the bridge and it was less than 10EUR to drive to Vatican/Colosseum/Borghesa. Alternatively one can walk 20-30min.
2. The neighborhood is full of bars/restaurants. We relied on TripAdvisor for selection/reservations and the food was remarkable. At night, one can just go to one of many bars downstairs for a couple of drinks.
About the apartment: the building is very old, the apartment is in excellent condition and stylishly decorated. There is elevator and staircase is in mint condition. It has two bedrooms, one sofa bed and two bathrooms. You need to take stairs to each of the bedrooms, which may be a problem for small kids/older people (this is clearly stated in the description of the apt.).
It is very lively outside, but windows suppress most of the noise and it was not a problem at all. Kitchen seems to be ready for any culinary adventure, though we spend most of the time outside and used just microwave and fridge for a quick breakfast.
Cecilia is a wonderful host, promptly replied to our questions and was on time for check-in/check-out.
