Staying at Kwanruen Park Hotel in Nakhon Ratchasima
I did not stay at this hotel, but visited it during an inspection trip. The hotel has private parking, free wifi and swimming pool. Rooms are clean, modern decorated and look comfortable. The standard rooms behind are a bit small. The front-side rooms have great view over the lake and the Suite room is really great and good value for money (2200 Thai baht).
It is a great location, if you have your own transport as it is a bit out of town, although there are a few nice restaurants along the lake. Unfortunately I lost the name-card and I cannot find any web-site of this hotel, but the location is HERE.
