The flat is absolutely worth the money. Amazing location - just 10 minutes by foot to Colosseum and about 15 to piazza Venezia.
Apartment itself is spacious and clean, more than enough for 2 people.
Though, kitchen appliances make noise during the night, so if you are a light sleeper - take it into consideration. For us it was not a problem:)
I would definitely recommend this place to everyone, and I would like to thank Melania for helpful tips and quick responses.
