the place I highly recommend close to everything including the place of interest , the room is neat I like the terrace. under the flat there is a shop selling the bus ticket. if you want to go in collosseum just simply catch the 916 bus going to piazza Venezia it's a walking distance but if you wish not to walk too long there is a bus going there only 2 stops from P. Venezia. the owner is very helpful we definitely back.
