Tasos' flat is all about location. I stayed there for almost one week with my friend and it was an amazing experience. We almost only walked all the time, as the flat is close to everything – from landmarks to really cool bars. The flat itself is also great and it can easily fit four people. When choosing your room, just keep in mind that the front one can be a bit noisy in the mornings if you are more sensitive to it. It wasn't a problem for me. Tasos was always fast on his replies and easy to communicate with. I would stay at his flat again anytime :)
