Well first of all, let me apologize for any inconveniences caused during your stay with us. We will put extra efforts to make sure that cigarettes smoke will not be present inside the building (we have given that 'room' a notice and they will leave soon).
As for other 'troubles', the key tag (controls electricity) and key card (controls accesses) are bundled together but can be separated to fit your needs. We might have not been clear and tell you upfront about this but apparently it has never been an issue with any other guests at all. As a matter of fact, we take great pride in giving the most secured (and somewhat advanced) access control system for any accommodations at this level in this area.
Lastly, we understood that our location is relatively far away and located deep into the alley (approx. 1.1km from the main road - Ladprao Intersection) and we have been honest to tell every guests 'before' they decided to stay with us. If the guests are okay about this, then they are most welcome to spend a night or two here. (And yes, we also gave them advice about how 'local' people commute which is clearly by motorbike taxi service.)
Anyway, I sincerely wish that I could have done better to serve and provide good quality service at an affordable price to you and everybody in this Airbnb community. If it fails you, I have to say sorry again and will try to improve the service in the next opportunities.
Thanks a lot for giving us a review.
