Great clean room will all the essentials and some extra surprises like a coffee machine and breakfast snacks which we really enjoyed. Location wise it's both a short walk to a metro station as well as areas to shop and eat. We had no problem walking to the Acropolis from the room as well.
Vivian was very helpful as well, assisting with things to do, helping arrange arrival and checking in on us to ensure all was going well.
This studio is highly recommended for a couple looking to explore Athens.
