Lovely and spacious, clean, very good facilities and really nice decor. It's in a great location, with bakeries, coffee and nice restaurants on your doorstep. Evangelismos metro station is just a few minutes walk away too. Marina, the host, was super quick at answering questions, which was really appreciated. Only negative really is that it is dark with regards to natural light, but if you're doing a short city stay you should be out all day anyway! Note also that the living room area balconies are only suitable for narrowly standing on.
Thanks!
