I can't say enough good about Corso37! It was spotlessly clean, artfully decorated, and the beds were the best nights' sleep of our whole trip! We hated that we were only there for 2 nights! I couldn't imagine a much better location--it was close enough to walk to almost any site in Rome, but far enough away that we didn't feel like we were in a tourist trap. We felt very safe and the AC worked well! We had 4 adults and 4 kids--the adults took the fantastic memory foam king size beds and the kids slept on the comfortable queen sleeper sofa and on two comfy single cots. Maurizio was a great host--he made us feel so welcome, gave us some eating suggestions, and even had coffee with us before we headed out to see the city! He also arranged our very early transport to the airport on the day of our departure which was a big help.
