I absolutely love and recommend this place: spacious, super clean, near a metro station 4-5min walk, also same time to many restaurants and cafe.
Two blocks to the right there is a traditional Greek restaurant that is great. Try the grill octopus in beans and vinegar. Uhmmm.
I am specially thankful to Dimitrios for helping with my bag. I have been traveling 6 months so my bag is 26kg and he made sure to be there for check in and check out to help. That is priceless.
