Konstantinos is an extremely good host. Prompt in his communication. What you see in the pictures is what you get.
The apartment is tastefully done with all amenities. Comfortable.
The best part is the location. Located so close ( walking distance)to most of the important tourist attractions. Close to Plaka and Adrianou the centre of Athens' active nightlife.
I strongly recommend Konstantinos apartment for visitors to Athens interested in sightseeing and the nightlife.
Only negative - of the two rooms only one has an AC. So if you are planning a holiday in the peak summer months bear that in mind. Also if you have heavy luggage note the apartment is on the Second floor and there is no lift. Besides these points it is a wonderful place to stay.
