I only stayed for one night, and really enjoyed it, except some problems with the shower (see below).
It's exactly as advertised - beautiful, cozy, spotless clean, comportable bed, enough storage space, super communicative host, easy check-in/out, and the small patio is so cute!
For light sleepers - it's very quiet and the bedroom can be completely blacked out.
Location was amazing for me - 5 minutes walk south of Keramikos Metro station, in a small street just a few steps from Konstantinoupoleos Ave., with a Galaxias supermarket just across the avenue. Plaka is a bit further away (~30 min by foot, 15 min by Metro), but it's still super central, and I liked the Keramikos area better :)
Re. the shower - it was perfect... but only for a quick 5 minutes shower :) after that, the hot water ran out, even after I turned the water heater on for 2 hours. Also the water drain was quite slow... so I'm not sure this would be a great experience for a couple or long-shower-fans. Maybe I got it wrong and didn't heat the water correctly? 🤔 I don't think so. Anyway - I'm sure that Dimitrios will take care of this, because other than that - the place was perfect.
