My partner and I stayed in Sevi's flat in Excharcia. The flat was clean, and welcoming. We enjoyed our coffee on the balcony and the really good Greek restaurants and cafe's nearby. Sevi was available via whatsapp whenever we had questions. We would definitely recommend this flat and neighborhood for people who are comfortable in alternative neighborhoods with rich political history, street art, markets, vegan food (also some Greek food is by default vegan).
