We stayed with our family for 2 weeks in Zelman's house and had a wonderful and relaxing time in Mount Martha. The house was large enough to cater for nine of us and very comfortable and spacious. The sea view from the living room is amazing and the swimming pool is really a plus.
Zelman's indications to access the house were very clear and the communication with him was simple.
The only down side was having the gardener trimming the hedges on the first day of our stay. Not ideal when part of us flew in from Europe the day before..
