Our stay in Efi's appartment was in general good. The location is OK but it is extremely dangerous when you come back from Heraklion by bus as you have to walk through the main roadway for few minutes (in completely dark) with lots of cars and trucks driving very very fast next to you. That was scaring! In addition, one night we had to come back home by taxi as the last bus was at 10.30pm and they told us that it was, for instance, at midnight. We had to pay a lot of money for that.
Also, the beach is not as close as they say in the description. We hitchhike to go there as by foot it was about 30minutes walking under the hot temperatures of August.
They helped us a lot via telephone when we had some troubles (such as some problems with the toilet noise).
Finally, they don't have a bin in the apartment and that was quite a pity for the cleaning work at the end of the day.
