Things we liked: Location is good - away from crowds but close enough to walk to nearby attractions. The neighborhood is quiet. We enjoyed sitting on the balcony with a beer and the beautiful view of the acropolis after a long hot day. When we missed our flight, I messaged Daniela to explain the situation and she was quick to reply. AC worked well which was greatly appreciated after hours of walking in 90 degree weather.
Things we had a hard time with: The washer. We're unfamiliar with European appliances and there were no instructions on how to use the washer (which was more complicated than expected). We ended up having to look up YouTube tutorials and wing it (after plugging it in which could only be done by plugging an extension cord into an outlet outside of the bathroom). Secondly we needed to do more than one load of laundry but found only one pod so we were unable to wash all of our clothes. Were these the end of the world? No, but we were really counting on being able to do laundry and the entire process became frustrating and lengthy. We didn't have a lot of time in Athens (our short time was cut even shorter due to missing our flight) so we just made do with what we had.
I'd still recommend staying here because everything else was fine, but the washer issues really put a damper on things for us.
