Marco's apartment was perfect! It is in a very good location (among other apartments, hotels, excellent restaurants and 10 min walk to the main train station & metro).
Marco was waiting for us, with a tasty bottle of white wine and a cool flat. There are 2 aircon units, one in the bedroom, one in the living room; which is such a relief in the hot weather.
My partner was very happy with the provision of a cafetiere and the microwave came in handy for warming up yummy leftovers.
We had a lovely stay and Marco was a great host, giving us top tips for our visit. (e.g. If you're going to the Colosseo, make sure you go in the Palatine Hill entrance rather than the standard main one at the colosseum - there were only 20 people in the queue!)

Thank you, Marco!
