I had a great stay at Lukas'. I really enjoyed staying there: it's a very friendly and large apartment with a beautiful balcony. There is everything you need inside, even some Ouzo ! Lukas was away but we had a very nice and easy discussion via emails to organize my arrival. Besides, his cousin Natasha was here to welcome me and make me feel home. Everything was easy and nice.
The flat is located in the middle of a Greek and not touristic area (which is what I wanted), you will find many bars and restaurants where you can spend a lovely time. It's a 30-40 minutes walk to the city center, which is a good way to discover the city I guess.
Perfect stay for me then: easy, confortable, well located ! Thanks Lukas and Natasha.
