The apartment is really well located, just besides piazza del Popolo and the Villa Borghese. You can easily access to all touristic places by foot. The flat is huge. We were 9 girls and we had enough privacy. There is a big kitchen with basic furniture and a terrace, perfect for relaxing a little bit after the long days of walking in Rome.
Indeed the tram is in the street down the building but there is AC in all the rooms so you can sleep at night. Just take earplugs in case you are a light sleeper.
Massimiliano was really nice and helpful. He gave us some advice on places were to eat and was very accommodating.
I would definitely recommend to stay at Martina A Piazza Del Popolo !
Thank you Massi for everything !
