I had a really nice stay at Frank and Soledad's apartment. The place was really nice and clean, and the location was also quite good. Furthermore, the host was really nice and helpful. He provided us with a map of Rome and took some time with us to highlight the different things we could visit. One of his tips (about where to buy the Colosseum tickets) saved us a lot of time as we didn't have to wait in the long Colosseum line.
