This is a great apartment. It is spacious, clean, quiet and very comfortable. On top of that, it's in a great location with the Acropolis literally down the street. The narrow balcony overlooks a nice walking street which becomes a really beautiful walking street as you get closer to the Acropolis and Anafiotika.
We had very hot weather and the apartment stayed cool. The welcome book the Upstreet team has put together should be a model for how to do these things. Accessing the apartment for the first time was smooth, even after travelling many hours. I only wish we could have met Konstantinos, but communication was always great. Highly Recommended!
