These are two separate apartments, one above the other, and they work great for a group. Both apartments are small, especially the kitchens and bathrooms, but the bedrooms are a comfortable size. The roof terrace is great, we ate out there and played cards in the evening. The location is perfect, walking distance to everything we wanted to do. Lots of noise and people outside the door pretty much constantly but with the windows closed the apartments were quiet enough - a bit of noise is a small price to pay for the location. There is a restaurant downstairs (you have to walk between their tables when you leave the building) where we ate and the food was excellent. About a 5 minute walk to Monastiraki metro station which goes to the airport so very convenient. All in all, a great choice to explore Athens from.
