Kaitlyn was an excellent host, and the flat was exactly as we expected from the ad. There's a metro stop and a train stop very closeby, which is very convenient, specially if flying to Fiumicino airport. We walked by foot every day to the old city as it was a nice walk, but it takes a good 40 mins to the Colisseum, a bit longer to the other sites. Overall we had a great experience in Kaitlyn's flat, and would undoubtedly recommend it.
