We've spent a week at Dimitris' place, and overall it was a great experience. We traveled as a family of 4 adults and a 3y/o, and there was plenty of space for everyone in the apartament. There was a special bed for our daughter, and she loved it! We also found some toys for outdoors - great to play in the sand on the beach (that is 4 mins away by foot btw). Supermarket is very close, that's also convenient. We used this location in Kissamoss to actually discover all the beaches from the postcards - Falassarna, Elafonisi and Balos - all in an hour or less from the apartament by car. We also went to Chania and Rethymnon - wonderful towns and the cuisine is superb.
As for the host, Dimitris was very attentive and kind; we checked in aroun 2 A.M - he was there to welcome us; I asked for some restaurant recommendations - there were they, 5 mins later. So again, nice stay in a nice place - definitely recommended, especially for those traveling with kids.
