I stayed for 6 nights in the blue room. Kristina’s apartment is very nicely decorated and has everything you need (equipped kitchen etc). Besides me there were several other guests, so the only issue was the bathroom that was blocked sometimes ;) The location is very nice, close to bars, restaurants and also next to a nice park and a hill where you can see all of Athens. It’s a bit noisy since there is a big street close by. All in all a good place to stay for a few days. Kristina and her housekeeper were also very nice.
