We were very pleasantly surprised at how the Barton was one of the more economically priced options but still in the heart of Plaka. All of the major sites were within a 15-minute walk, and two metro stations were each 10 minutes away.
We had some questions during our stay, and our host was very responsive, either by phone or email.
In summary, a very clean, comfortable, and safe place. There are more luxurious options in the area, but the location-price combo was fantastic.
