My family of 4 had a great stay in Athens at Nestor's apartment. We found Nestor to be an amazing host, his communication was extremely quick and he gave us heaps of helpful tips when we needed to ask questions. The apartment was as described and our kids loved having a double bed each!
The location was an easy walk up to the Acropolis and there were plenty of places close by to eat out. I recommend Just Pita for some delicious gyros. While the location may seem a little unsafe we found it perfectly fine and we're happy to walk around with out two young children, we had no problems at all.
The price in particular was great!
