We received detailed check-in instructions from the host before our arrival. The self-check-in was smooth. The building was nicely updated. The building shows a lot of design elements. . Our 5th floor apartment has a nice floor-plan and comfortable living areas and bedrooms. Nice to have instant hot water in the apartment. The street side balcony is fairly big and with an open view to the hill some distance away (beautiful night view too). Nice to have breakfast outside on the balcony - nicely equipped with outdoor furniture. An informative binder was provided.
The building is situated in a more "local" neighborhood. We caught the chance to shop at the Friday-farmers market. We cooked a good dinner with the farmers market and grocery store purchases (very reasonably priced). The neighborhood is a little distance away from the "touristy" parts of the city. However, some stores and restaurants are scattered nearby but fewer selections. Some walking is needed to get to the main tourist areas. It was workable for our group with no children and all of us could walk at a good pace.
We really enjoyed staying at the apartment. It had a comfortable feel to it as soon as we walked in. It is definitely a nice place to stay if you want to experience the less "touristy" side of Athens. A good place to relax.
