First of all: we will come back to Rome although we couldn't throw a coin into Fontana di Trevi because of the current restoration.
And yes, we would come back to this apartment because it is spacious, well furnished and perfectly located near by the Colosseum.
Rome is a nice but busy and noisy town. The busy road is unquiet also at night (cars and street cleaning), so we recommend ear plugs for a better sleep. Otherwise it is the perfect apartment for a city tour.
Giancarlo was a good host, although we didn't met him personally. The communication was perfect - in the forefront and while our stay. There had to be a change of apartment at our last day because of trouble with repairs in the neighbouring flat. Giancarlo organized a very good apartment in the neighbourhood, so we had no problems.
