We have used quite alot of airbnb, and we can say without any doubt that our experience with Riki has been the best one we ever had. We went to Kos only for 3 days and we did a lot of different things thanks to her recommendations. She told us some really nice restaurants (traditional Greek cuisine, fresh fish restaurants, and others), she even did a reservation in a restaurant in Zia for us.
She also told us a lot of places to visit, as the Asklepion and other Greek ruins, and some of the best and less crowded beaches on the island. She also sent us to a really nice boat-trip to do some snorkeling for the whole day.
The apartment is a bit difficult to find as the street has no number, but she was super nice and with her help, we found it in 10 min. It is less than 10 min away from Kos (5 by motorcycle) and it's really comfortable. Thanks to the two air-conditioners and the nice design, you can have a relaxing stay in the apartment. It has also a kitchen, so you can cook everything. It even has 3 different coffee machines, everything for all different tastes!
To sum up, if you have the chance to go to Riki's place, don't hesitate and book it! She will give you the best recommendations to enjoy the island for sure and the apartment is really nice.
Again, thanks Riki for letting us stay in your apartment!
