The hotel room isn't big but that's what you pay for. The room is comfortable instead, with a big and comfy bed,, and well-equipped, so the room size didn't bother me.
It takes 10-15min walk from Ekkamai station, but there is a shuttle service to Ekkamai every hour. There are some shops, restaurants and bars on the way. Big C and Starbucks are just in front of the hotel.
If you want to stay at Ekkamai and with little budget, this is a good option!
