My girlfriend and I stayed at Matteo's place for 6 days recently and were really happy with the whole experience, from booking to being dropped off at the airport for our flight home.
From the start Matteo's communication set us at ease as he provides clear instructions on different ways to get to the apartment (some in video form) and easy to follow guides on the amenities in the immediate surrounding area. We opted to take Matteo up on his transport service, during which he gave us a real local insight into the best places to go including landmarks (some of which I was unaware of even though this was my second time visiting Rome), restaurants, bars and recommendations on how to avoid some of the crowds for the main tourist spots.
Throughout our time in Rome he was always on hand and made it clear we could get in touch any time. He continued to provide more tips on places to go around the city, some of which came in really useful. We ate at some of his recommended restaurants and were not disappointed!
Beyond all of the local knowledge the apartment was really nice and cleaned to a really good standard. It made for the perfect base for exploring the city as it's ideally located within walking distance to the Trevi fountain and Spanish Steps. Other landmarks such as the Colosseum are (at a guess) around a 20-25 minute walk away (and really fun to wander to through the winding historic streets of the city) but can also be easily accessed via the metro station just down the road.
We'll gladly book here again, for the location alone, but the standard of service the Matteo provides in a nice laid back manner is something I'd recommend to anyone.
