Andrés is a great host. He's very helpful and even made it possible for us to check in earlier than usually. He even left a bottle of wine and water for us which we really enjoyed :)
The flat is exactly as described. The jacuzzi works perfectly and the view is stunning. The location of the flat is also great. We walked a lot but you can also use the subway which stops 2 minutes away from the flat.
I can only recommend this flat to anyone planning to visit Athens :)
