The listing description was accurate; we had everything we needed and the house was very clean and comfortable. Our host was very friendly and gave us all the local information we needed. He was easy to contact with any questions we had.
Kolymbia itself is very busy in August and it is very much a tourist destination but with a car it is easy to access quieter places e.g. the west coast. It is also well-placed for visits to Rhodes Old Town and Lindos both of which are well worth visiting. The mountains are just above the village and the views spectacular from them - also well worth the climb (and if you don't want to walk, you can reach the steps to Tsambika monastery by car).
The 'supermarkets' in Kolymbia itself have a limited range of food and if you want to cook your own meals a ten minute car trip to the big supermarket near Afandou is required. This was no problem and the kitchen equipment provided is quite sufficient for self-catering. The local taverna (Michel's) is however also very good and quite cheap.
