I really enjoyed my stay in Marinas Penthouse. It’s all exactly as described: The room is small but even for al longer stay, like I had, it was fine. The bed is super comfy and although you’re right in the Center of Athens it’s perfectly quite for sleeping and working :)
The balcony is spacious and you can experience there a nice feeling of being exact and high up in the centre of Athens ☺️
Since I stayed here in February there was no sun at the balcony but I suppose that in summer the sun is higher. There is a perfect heating in the room so that you can easily stay there in colder months if the year.
All in all I really recommend staying in Marinas House - she is a really open, helpful and great host. The communication with her was always easy and quick.
