I had a fantastic time in Marco's place! The location is just brilliant, in the centre and easy walking to so many highlights, including the Colosseum and the Vatican. The square nearby is full of life and great fun through the day and the evening. There are good restaurants, cafe's and bars nearby as well.
Marco was a great host. He was easy to communicate with, responded quickly and accommodated an earlier check in for me. He had plenty of suggestions for things to do, restaurants and money saving tips. He was inclusive, welcoming, and generous. He was also very happy to organise extras like a private transfer, though I didn't end up needing it.
The room is plenty big enough and the bathroom (incl shower) is a very good size. The rest of the apartment is also nice and the terrace is a real bonus - so lovely! The only point I need to mention is for the hot months. There isn't any air con, though there is a small fan. For much of the year this won't matter. But if the heat gets to you and you're travelling in the height of summer, it's worth noting. The windows allow some ventilation and the terrace is something of an oasis, especially once the sun starts to drop!
Overall I had an excellent time and I'd recommend Marco and his place to anyone. I'd love to come back!
