Rooms looks a lot better in real life than on the pictures. Plenty of space, with two big windows. Enjoyed the A/C too. There is only 3 rooms in the whole apartment - no problems with shower/bathroom.
Host provided us very detailed instructions on how to get to the apartment, and some recommendations on places to eat nearby.
Very well located - haven't used public transport even once - ~20 minutes to colosseum, ~3-5 minutes to piazza navona and pantheon.
Would totally recommend!
