Amazing place. It's central, cosy, warm, comfortable and calm. Argyro thought of EVERYTHING from food to toiletries to medication to umbrellas... Even Netflix! The first night we were a bit surprised because we took small adjacent roads to come back home and there were a lot of homeless people and immigrants just standing in groups on the sidewalk so we felt very uneasy (there were no incidents. None. They didn't even talk to us). Still, we quickly found alternative routes.
The rest of the stay was perfect. Argyro gave us tips regarding what to do and she was very reactive. We got to Greece very early in the morning and she accepted to give us the appartement before the indicated check-in time which was awesome because we got to rest.
I highly recommend staying there.
