Staff speak minimal English although they tried their best to help me out when I was here during lockdown. They were extremely helpful when I forgot clothes in the closet and had to go back later.
Sadly, the advertised wifi was minimal for phones and non-existent for my laptop, so if you need to work, be forewarned.
Room was clean BUT large black ants came out at night, and woke me twice crawling on me! Had to sleep with all lights on and a mask. Seemed to come up the drains; never experienced this in years of budget hotels in SE Asia.
In short, stay downtown and use cabs or transit if you have business in Bang Khae.
