We had booked a 5 day stay at the villa of Nikolaos. We however decided to leave the villa after one night. The villa did not give us "that holiday feeling". The house has plenty of room, but it needs some necessary maintenance. To name a few things: the pool table balls need replacement, the suggested ping pong table on top of the pool table is a nice idea but in reality not very functional, a shower curtain in the bathroom of the main bedroom needs to be put in, blinding curtains on all bedroom windows that do not have shutters would be a welcome addition.
The plus side: the pool temperature is absolutely lovely (although the pool is really on the small side), the outside area is nice with an outside dinner table and BBQ. Nikolaos was warm and welcoming upon arrival. He showed us the house, and gave tips for local restaurants, he also provided some drinks and same grapes as a welcoming gift.
The area around the house is not too nice (in our opinion), the area feels a bit shabby. The town is small and there is not much to do there. The beach is relatively close by, but unless you are a kite-surfing fan, definately not the nicest beach area of the island. Rhodos city (old town) is a 20 minute car drive away.
We would NOT recommend a stay here, unless you have a very specific reason to be in Kremasti. If you do, then his house is a good place to be (and even better after some maintenance is done).
