I really enjoyed my stay at Katerina's. I stayed for a full week and found it was in a very nice area, very quiet at night so one could sleep well. I always got the trolley bus into Syntagma square which was easy (no's 2, 4, 11) any time of day or night. At night I could wander around Mets feeling very safe. Amazingly only 5 mins walk to the renowned jazz club: Half Note !! Lots of nice tavernas, bars etc. in Mets. Katerina was friendly, and kindly helped me with my Greek. The small hostel was great for one person but two people could easily have been comfortable there. Megaritis is an excellent place to eat dinner. I would definitely stay there again.
