Great place. Feels brand new. Very clean. I was there the coldest week of the year (4 C) and the heating worked very well. Comfortable bed, nice shower, good WIFI. Secure building. Just a 5-minute walk from the lively neighborhood around Monastiraki square. The streets for a couple of blocks around the building have quite a few immigrant men standing around, but i never felt unsafe; I rather got the impression they were trying to stay out of trouble. I hope i can stay there the next time i visit Athens.
