I didn’t have the chance to meet Akis &Marietta in person, but they reply messages very fast, with good manner, and happy to help however they can.
Their apartment was nice and clean, provided everything I daily needed, everything they promised worked really well.
The neighbor hood is quiet and safe -probably the safest place you can ask. Of course, in exchange if you’re looking for lots of interesting restaurant, shops or tourist attractions, you’ll need to walk a bit or take the metro to other parts of Athens. There are several supermarkets and cafe around thought, the place is convenient enough to live in. The apartment is like 10 minutes walk to Ambelokipi metro, the station is on the line to airport, so it’s quite nice that you don’t need to carry your luggage to change metro lines. It won’t take too much time to get to the museums ,to Evangelismo, Syntagma or Akropolis metro stations, which is not bad. Overall, I had a good time there. If you’re looking for somewhere safe, quiet and cozy to have good night sleep, this is your place.
