The flat is exactly as advertised, the photos are real and the terrace does feel like a slice of heaven. I would fully recommend this flat for a couple or even three people if you're on a budget.
The flat is located on a quiet residential area but 8 minutes walk there is a very trendy square to have some drinks and food.
Vivian and Minto have put a lot of love into the place and you can feel it! They have lots of info at the house to understand how to get to central and how to maximise your stay in Athens. The mother of one of the two received us and she was lovely!
Please remember this is not in the city centre and you must use the metro to get in and out, the metro is good but it's almost always full. The busses are not really reliable but 15 minutes walk to Victoria is nice.
Highly recommend it!
