This was a really good spot for our family of four (with 2 kids). The apartment itself is very comfortable with modern amenities. The location is central with an easy walk to the Acropolis, the Museum and the area of Plaka. Its also a quick car ride from several points of interest. If you are looking to do a day cruise to the smaller islands, pick up location is around the corner from the apartment.
Catherine was a good host and very responsive. She provided a few recommendations which turned out to be really good. I highly recommend a stay in Catherine's apartment.
