Daniel was very welcoming and met us at the apartment at the agreed time. We struggled a little finding the apartment, I would recommend bringing a map with you when you come! It is about a 10-15 min walk to the nearest station, which has a metro which will take you to the Colosseum etc.
The apartment is nice, compact with a little kitchen area and sofa, nice bathroom and spacious bedroom. There is no internet access which makes planning your days a bit more difficult, but Daniel has provided several tourist guides of Rome and maps (not many in English though) which we used to help us instead.
Also found some nice restaurants near the apartment - as its not in the centre of the city they aren't necessarily designed for tourists so prices are a lot cheaper than in the centre and the food was delicious.
All in all it was a great apartment at a reasonable price, suitable for a couple who don't mind travelling a bit to get to the town.
