This property has a few issues, but is still a great place for easy access to the Colosseum. (Down two side streets, and then you literally have a view of the Colosseum for the rest of your 10-15 min walk, with a great gelatteria on the way!)
It was not the most comfortable, but it was ok. Double bed is a fold out couch, and tries to collapse on you if you put your weight in the wrong spot. The other rooms had a King bed and single bed, both were comfortable. Two chairs were broken.
It is a long staircase up to the unit. We could not get on the WiFi (and we had no trouble anywhere else). In fairness, we were only there one night, so we did not bother to contact the owner about this.
You have to call someone to arrange a time to get in, and he kept trying to shorten our stay from what was agreed upon in advance.
We did not attempt to use the kitchen, except for a cup of tea, but we were unable to figure out how to warm the water. Bathrooms and keys worked well.
