Friends from 3 continents arrived at the Benviar Tonson Residence in July (and of all times Big Buddha Day with no alcohol for 2 days!). Anyway, the hotel had informed us a week prior to our arrival that the 4 bedroom we booked was unavailable due to maintenance but was very helpful along with hotels.com to replace us with a Premium 3 bedroom + seperate 1 bedroom.
The Premium 3 bedroom was very nice. Nice view, good sized balcony, full kitchen, working laundry, good entertainment system with projector and good size bedrooms and beds. The only feedback I'll give is that a proper sofa would be much more fitting (and comfortable).
Location was good... definitely walkable to the BTS but we mainly rideshared around due to the rain. Often took about 15 mins to/from Central World with the jam which is about the same as if on foot.
Service was efficient. There were an army of cleaners and maintenance that kept the rooms at tip top shape.
Overall, I loved it and will definitely stay again.
