We had a nice stay at Deni's. The apartment is centrally located: around the corner from the shops and restaurants of Plaka, a 10 minute walk to Syntagma square, with a nice rooftop for an evening or morning drink. The first night we arrived the family was having a barbeque and the music was very loud, but they turned it down immediately when we asked and very kindly invited us to join. Overall would recommend.
