Athena is friendly and wonderfully responsive. This studio has the essentials down, is as pictured, and is of good value. The shower is a highlight after a hot day of sightseeing. Walking is manageable, and it's easy to take a car to a restaurant or sight for 3-6EUR. Blackout shades helped us sleep well.
My reservations primarily have to do with the building, which is not a luxury space. As listed, there is no doorman. Also, the front entrance was never locked during the time we were there. The lobby, stairwells, and hallways are not lit by default, which can make the place eerie if not accustomed to it. One evening, as we were sitting quietly in the room, an old man knocked on our door. (He went eventually went away.) We hadn't been expecting anyone, so taken together with the other aspects of the building, it was creepy. We felt reasonably safe due to feel and repute of the neighborhood but were more wary than we wanted to be on vacation.
