We had a wonderful 4 nights at Franco's truly special apartment.
The apartment is comfortable, quirky, and beautifully classic with signs of its wonderful history in every corner. Previous comments have said it was cold, but this was not our experience - for our February stay the temperature was perfect and we were very cosy. One word of warning - the apartment opens right onto the street, which means it can be a bit noisy, so very light sleepers might take note. But I'm a light sleeper, and I soon adjusted - it's kind of lovely waking up slowly to the chatter of Italians on the pavement :)
You could not wish for a better location - we were within easy walking distance of il Colosseo, and travelling all over the city was easy because the tram and bus links were incredible. We could get everywhere we needed to get to within half an hour, it was the perfect location.
The neighbourhood is busy but felt very safe, particularly important if you're unfamiliar with the city and coming home late at night. Franco was a wonderful host, a gentleman and so helpful, booking us a cab to the airport and responding to all queries before and during our stay extremely promptly. Thank you for everything!
