We had a wonderful stay in Monica's place. Her instructions and guidance was amazing, and we had everything we needed (including AC and a powerful fan). The location couldn't have been better and allowed us to explore more of the city. The apartment is well laid out to provide lots of space to lounge and cook. I did find it a little dim having only one window, but we weren't really inside during the day much anyway.
We had some issues with the AC leaking onto the ground the first day. There were plastic containers placed to catch the leaking water, but they had initially been misplaced and soaked through one of our suitcases. We were also not instructed about their purpose of the containers or that we would need to empty the containers after a few hours of running the AC. That would have been useful instruction, but we learned the hard way and it wasn't a big issue the rest of the trip.
Overall we really enjoyed our stay and would stay here again the next time we're in Rome!
