The immediate area surrounding the exterior of the penthouse stay is very questionable at best.... it is inundated with trash outside the building and the smell of marijuana permeated the first-floor entrance to the elevator as well as the stairwell once you disembark the elevator on the 6th floor. There were a group of teenagers that looked to be smoking something, but I couldn't ascertain if the smell of marijuana was coming from them or not. There was a white powdery substance on the stairs on the top floor, that leads into the penthouse similarly there was trash on the stairs (plastic bottles) leading up to the penthouse stay (pics were included) and the area(s) are in disrepair; paint peeling off the walls, ceiling. The rug outside of the elevator on the first floor was wet and we smelled urine. Upon entering the penthouse, the smell of cigarette smoke filled the first room, my wife immediately began to have an allergic reaction to the smell of the cigarette smoke. After further observation, it was noticed that there is only one bathtub/shower for the entire penthouse where 9-guests were scheduled to stay. I notified the host upon entering the building and the penthouse of this issue. We decided this place was not accurately reflective of what is advertised and notified the host of our dissatisfaction with the state of the stay. Lastly, upon exiting the elevator on the first floor, we were accosted by a young man who was not wearing any pants and was making facial expressions as if he were having some social or mental breakdown! This upset my wife and my brother-in-law who was visiting from the US. Immediately after exiting the building, I called the host an explained our concerns (both safety & cleanliness). He immediately informed me that he had access to the video camera on the first floor and could the teens. He also mentioned he knew one of the teenagers that were congregating near the entrance to the elevator as a resident in the building! I asked him to call the authorities immediately and that we would not, could not, stay in the location for obvious safety concerns. My family and I were forced to seek accommodations elsewhere and the costs for these were significantly higher than normal due to the last minute change in plans, brought upon by the less than acceptable standards.....we were being charged nearly 900-1000 a night to stay in this penthouse stay, which is totally unacceptable. The only positive interaction we had during this event was with the host who communicating with us. Even after this transpired, the Host charged us a full night stay! We immediately submitted this concern to Airbnb and their "investigation" resulted in the determination by the Customer Service Rep, that the Hosts was right to charge the one night stay. Guests be very cautious about this stay.
