Nikos was a great host, providing us with information on the local supermarkets, restaurants and taxis (all a 5-10 minute walk away). The apartment was just like the pictures and came with everything we needed for our stay, including good air con which was perfect in the hot weather. The roof top terrace has amazing views and is what would make me really recommend this place. It is slightly out of the city centre but in my opinion it's worth it for the view and to be in a quieter residential area, plus taxi's are cheap (around 7euros) to get into the centre.
I would recommend this apartment for anyone looking for a relaxing city break in Athens.
