Carmela's place was just as described and in the cutest little neighborhood. The Colosseum is right at the end of the block and the apartment is perfectly walkable to all the great sights Rome has to offer. Everything was clean and tidy and we had no problems meeting up with her colleague Katerina to let us into the apartment on arrival. The bed was super comfortable (although I can't speak to the additional bed in the living room, my friend had no complaints). I'm not sure you'd be able to sleep 4 in the apartment as the additional bed looked like a single to me but maybe there's a way to pull it out that we didn't see. We only had 3 people so we didn't make an effort to check it out. It was exactly the type of place we were looking for. Thanks for a great stay!
