I had three massages during my stay at the Robinson Club Daidolos, all with Andre. I must say that Andre was amazing - he gave the best massages I have ever had. I had an upper body Deep Tissue Massage which involved the neck, head, upper & lower back, shoulders, arms & hands. The treatment rooms are basic, but they are clean and smell nicely of aromatherapy oils. The Wellfit Oasis Spa has an attached gym which has all the basic equipment and is part of the Adult area only complex (the resort tends to have many families with children). There is also a large adults only pool as part of this area of the resort, so its great to go for a swim afterwards.
Just so you know, the entire club caters only for Germans in the sense that all of the guests and almost all of the staff are German. I went with my extended family who live in Germany, so keep this in mind. The club itself was beautiful, but it is built on a hill so you end up getting great exercise just walking to and from your room. The weather is perfect is Kos as it was 32 degrees and sunny every day.
