We really enjoyed staying at Blue Horizons. The pictures are accurate and the place is beautiful. We went in early April though, and it was very windy and a little chilly so we couldn't take advantage of the beautiful outdoor space or pool. Check in and check out was easy. Make sure you use WhatsApp and provide your contact details and it is very easy. I loved having coffee available in the unit to make my americanos in the morning, versus having to go out and buy it prior to arrival. I also really appreciated the welcome gift and Cretan Raki.
Crete is large so having a car let us visit Chania and the old town area around the Old Port was great. We also tried several local restaurants and really enjoyed the fresh fish. Crete is definitely an outdoor place with beautiful beaches so if it's not warm enough to swim some of your options are limited.
Overall, we really enjoyed our time and the responsiveness of the host. The place is just like in the pictures and is very nice. The only issue we encountered was that the beds are very hard. Some may not be bothered by it, but I was considering buying a mattress pad in Chaina. Last thing is that the directions shown in the Airbnb listing took us to the beach versus the actual villa. To find the villa, just search on Google Maps for Blue Horizons and it shows up. Other than that, a really nice place that I'd recommend for a country-side Cretan holiday.
