Yiannis has a really nice and cozy place. Felt perfectly at home away from my own and everything we needed was there. Location was great, around 5 to 10 mins to Monastiraki and to great restaurant. It was a little hard to find at first but we found it nonetheless in the beginning. Place can be rather noisy till late at weekends, as downstairs there were several bars (and dogs barking frequently) . But luckily we were very tired from the tours and knocked out straight onto bed.
