Me and my family had a great time in Kostas' house. I had the chance to meet Kostas and his wife, and they are very nice people. The place is really confortable. The underground station is just four minutes away, and from there you can get anywhere really fast and easy. There is a lot of shop really close where you can go shopping, have a nice evening at the cinema or have lunch at the restaurants.
In the house, the rooms have a good size and the beds and mattresses are fantastic! The kitchen has all the amenities and is really easy to cook on it. The living room has a big sofa, tea table and another table that can accommodate up to six people. The bathroom is brand new, clean and fresh.
I would definitely advise you to stay in this place. I will be back when I have the chance!! Thank you Kostas!!
