Flora i Talay is at less than 10 minutes walk from the gym and it’s located directly on Klong Prao beach.
It’s a recent resort, the ratio price / quality is reasonable and the location on the beach is excellent.
The restaurant is serving Thai and European food. There is a kids playground and the swimming pool is small but enough to have fun and to cool down. They offer free Wi-Fi like most of the resorts and it’s possible to rent bicycle directly at the resort.
