Marco was extremely helpful and communicative. He kept in contact with us before we arrived and during our stay. Although the apartment is on the 1st floor, in Europe that means there are still stairs, and he helped carry our luggage up.
The bed and pillows are extremely comfortable and the large windows on the front allow you to people watch, but don't open the windows as the mosquitoes are voracious!
The location is perfect and puts you close to many sites, all within a short walking distance.
It was unseasonably warm when we were there and we had some problems with the air conditioning, but Marco responded quickly.
For dining, try Trattoria Giovanni and Locanda Fiorentina. There is also a great sandwich shop, All'Antico right around the corner.
We would happily stay in Marco's apartment again.
