A few years ago I wrote a review recommending this property for short term stays near BKK airport. Unfortunately, I can no longer recommend BS Residence.
First was an issue with the airport shuttle. When it arrived I asked that is wait for two minutes for my wife to return from the bathroom. She arrived in less than two minutes, but the van left without waiting, causing us to wait over 30 minutes for the next van, even though we were told the van would wait. There were no other customers.
The hotel room itself is spacious, the bed was comfortable, and we had a nice poo view, but the room was infested with mosquitoes. We killed nearly 70 of them (yes, we kept count). I brought this infestation to the attention of the front desk and was told that they would take care of it, but they did not. Mosquitoes are the main carrier of dengue fever, including hemorrhagic dengue fever, which is fatal.
The other issue was the bathroom. It looked like it had not been cleaned in years. There was soap scum and mold in the shower. The shower ceiling was moldy and disgusting. The tile in the bathroom was filthy. The hot water did not work. Based on the condition of the bathroom alone, we will not return to this hotel. This is not the first time we have encountered these conditions at the BS Residence.
