Its a lovely place and we just walked 5 to 10 mins to get to Acropolis and Restaurants etc. So we actually needed no taxi or metro. We went as a couple and it was good. We didn't meet the host though, so we had the place for us.
There is no door to your room, only an open stair. So if you need more privacy, i wouln't recommend it. But we had no problem at all.
