Great location, walking distance to most tourist attractions. If walking 20-25 minutes is not an option to Colosseum or 35 minutes to Vatican, there is a Metro station 2 minutes walking from apartment or you can take taxi for around 8 euros
Apartment is very nice , was sparkling clean and roomy for party of 4
Monica is a great host - very responsive, always on time and made great recommendations and also reservations to local restaurants.
