I have good and a few negative things about the unit.
Marco is a good manager and he responds to problems gets them addressed. He is helpful in terms of giving you guidance about getting around in Rome, places to see, etc
Now, the issues. First, the toilet nearly backed up, but we caught and reported the matter in time and it was fixed. Second, the shower refused to stay up and sprayed water on the bathroom floor. It was reported and fixed after 2 days. Third, the circuit breaker tripped four times during our five day stay; we were told that it was because too many appliances were on - not a good reason. Incidentally, we never had the ACs and laundry machine on at the same time. In short, there is a problem with the electrical work in the unit. Fourth, we weren't given dishwashing liquid, paper towels, dish cleaning sponge etc. at the start. Once we brought it to Marco's he had supplies sent the next day.
I think the problem is that the company that owns this unit has a number of others, which is not a problem in and of itself. The issue is that they have not created systems required for such a scale.
