My husband and I stayed here for 3 nights for our 13 year anniversary. The penthouse apartment is spectacular : Modern, tastefully decorated, well equipped and has 3 different terraces to enjoy stunning views. It is in a hip area with many great bars and restaurants, with a vibrant nightlife. It is slightly away from the crowded tourist hotspots, which was a great escape from croweds. All the main sights were 15-20 mins walk away - we did not use public transport once.
There is a great grocery store nearby and it is very easy to get to apartment from airport.
The bed we slept in was so comfortable we did not want to get up!
The best part is that the hosts are super friendly and provided us with so many fantastic tips to enjoy the area and beyond.
I cannot recommend Spyros and Anastasia's apartment enough.
We will definitely stay here again when we visit Athens next.
