Dina's flat is very clean, confortable and was recently renovated. The AC is particularly efficient and the balcony very lovely. The neighbourhood can be a bit unconfortable for women alone but you can easily get a taxi to come back to the flat at night (the fare is about 4€ from Monastiraki). Dina and her husband Eugene have been wonderful hosts, very welcoming and accommodating, they gave us great advice on what to do during our stay in Athens.
