Having been to the border area of Mae Sai I decided not to sleep there as I just don't like it.
The V-park is conveniently located across the street from Mae Sai bus terminal which makes it a good choice for us budget travelers. The rooms are large, modern, clean and comfortable. I paid a walk in rate of 500 THB which includes breakfast. I really enjoyed my stay here and would use this hotel again.
The only negative issue that I must point out is that there are very few eating and drinking choices in the area. Therd is a night market in front of Tesco Lotus, for lovers of Thai street food or KFC and MK inside the shopping complex.
