We have just got back from a fantastic stay at Bellevue! We spent 9 nights with George and Fofi and felt very welcome from the moment we arrived. Our room was great, right next to the pool and decorated in a traditional greek style. Food at the Taverna was lovely and really good value for money.
The plan for our stay was to do very little and Bellevue allowed us to do that with lazy days by the pool or either of the great beaches nearby.
If you do want to see the island there are buses to Heraklion and other areas but would recommend a car if you plan to do a lot of exploring.
