We only stayed on night at Domenico's and communication was amazing. He was great with offering help with directions and was very flexible with check in/out. The location was fantastic, and definitely a must-do if you are in the Rome area.
The reason we are offering 3 stars as opposed to 5 is because of noise level and wifi. The unit has 2 studio apartments, we stayed in the left one, decorated with a "?" on the door. After a dinner and a nice walk, we decided to head to bed early since we had an early flight the next day. All was fine, until around 3am when the guests next door came back and decided to watch TV. Usually, this wouldn't bother me, as who am i to say what you can or cant do, but the fact that the studio walls are so thin, that the TV sounded like it was in our room, is unacceptable. I could hear every line of the show, and also hear the conversation of the guests too. It was as if the walls were nonexistant, and paper thin.
The wifi signal was also very poor, and kept kicking us off every 5-10 mins. And could not load small 3min videos.
