I don't know what I can add that has not already been said by other reviewers.
The location was perfect. Super close to the Acropolis Museum, metro, and the Plaka; but far enough away from the hustle and bustle. The bakery, shops, etc. nearby give you a feeling of being a resident and not just a tourist. Ralou was great on communication before, during, and after the stay. She offered tips on where to go, and provided a detailed binder with instructions on how to use the AC, the stove, and the washer (all very welcome). The unit itself was larger than I expected, with plenty a large living room; the kitchen was nicely appointed with everything you need for coffee or making a meal.
I would not hesitate to stay again or recommend this location to other people. One of the best Air BnB experiences we've had.
