We really enjoyed staying at Constantinos apartment! The location was ideal for us: Kolymbia is not too touristic, it is in the middle of Rhodos city and Lindos so you didn't have to drive too long to get to these more touristic cities and the beach nearby (Tsambika) was fantastic! The water was clear, it was a sandy beach with the opportunity to do watersports, the beach was never too crowded, you could eat and have a drink at a beach bar - you basically had all you needed!
The apartment was very modern - what you see on the pictures is what you get and the best thing was the outdoor shower and the sunbed that we used daily. Furthermore, the apartment is very near to the busiest street of the village with restaurants and smaller shops but far enough so you wouldn't hear any noises.
Constantinos was very helpful and gave us great recommendations whenever we had some questions and he made us feel very at home during our holidays in Rhodos! I can highly recommend staying at his apartment, we had a great experience! :)
