Maria is great, very responsive and willing to help. she waited for us with late check-in and let us stay for late check out. the place itself is nice and in a very good location. Value for money is definitely there. Two things to improve iny opinion is AC for the winter, it is a bit cold even when it's on all the time. and the bathroom need some kind of better isolation from the living area. other than that I would highly recommend this place when visiting central Athens.
