Massimiliano's apartment was perfect for our needs. We had three nights in Rome with two small children and we really appreciated the size of and amenities in the apartment , as well as its location. The spaciously proportioned bedroom and a half were perfect for the four of us, the shower room was amply generous (we didnt use the other window shower) and even had a washer/dryer to use (so useful when travelling with kids!). We didnt need or use the terrace, it's up some tricky stairs with a gap the size of a two year old at the top.
As for location, we brunched out every day in the nearby piazzas, and walked from there to all the sights we choose to cram in: piazza navone, the coliseum, the forum, trevi fountain, villa borghese, the Spanish steps, the Vatican piazza too.
Another thing: Massimiliano was really helpful with our arrival, changing an appointment without us asking so he could meet us, waiting for our delayed arrival, showing us everything in the apartment, very relaxed with our very last minute booking. Grazie per tutti.
