The location is great - right on the metro. The room was so hot, I couldn't sleep. The owner said a repairman told him, "That's the we all of the air conditioners work." Of course, that's not true as I have had working ones before and since that time in Italy.
He also told me I should have told him sooner (instead of 10pm at night). I told him I told two of his workers earlier in the day and they said they would take care of it. He told me that I should have come to him. We went back and forth a little about why his workers weren't enough to tell (they should report back to him, I would think).
The manager did give us a fan which was ok. But, since I specifically booked a place with air conditioner knowing it would be one of the hottest days of the year, I was disappointed. The manager manages another place on another floor, so you have to go down to the other place since no one is ever at the desk in this one. Everything was very clean, however. Except this one glitch with the air conditioner, I think I would have rated the place pretty well.
