Short version: The place is really comfortable, clean, and pleasant. It is great for one person, for two, it depends on what you're up to. I travelled for work so for me it was important to be able to to cook every now and then. Cooking for two might be a bit tricky...and the hot water is a bit short for two. The terrace is truly nice and the bed super comfortable.
Long version: I got t Athens a another place I had rented which turn out to be disgusting. I contacted Alexandros and Maria, co-host, replied immediately. I asked if I could see the place before booking it ( yes, I was a bit traumatized by my bad experience) and she agreed. She showed me the apartment and I booked it right away. Maria was really nice and helpful, which I really appreciate. As well, as said above, the place is designed for you to be comfortable. I really enjoyed the terrace, the desk is big enough to work, and despite being in the center the area is very quite. No noise. Plus, direct line to the airport which is truly a plus. Totally recommend the place.
