The apartment is in a great location, on a quiet street in a very fun neighborhood. There's a 24-hour green grocer and excellent bakery just steps away, as well as nice restaurants and cafes very nearby. Pangrati is not at all touristy, but within walking distance of the city center (or an easy ride on the 2, 4, or 11 bus) with some nice museums and attractions of its own.
There's plenty of breeze if you open the windows and the A/C worked well for us in hot summer weather.
There's a new washing machine that works well--just be warned in case you are afraid of heights that you'll have to lean over a 4th floor balcony to hang your laundry to dry.
The one big problem we had was with cleanliness. The apartment has a serious mold problem. Vasilios sent a cleaner who did what she could to wipe up mold from the closets and walls, but we're sure it will come back. We suffered from allergies even after the clean-up, probably because the mold is still inside the walls.
We found the mattress uncomfortable and a bit narrow for 2 people (it's 120cm wide).
Still, Vasilios was responsive to our concerns and was quick to help when something went wrong with the electricity or internet.
