When I arrived, there was a noticeable marijuana smell in the lobby, elevator, hallway, and inside the unit (likely coming from outside). I contacted the host, who suggested turning off the A/C, stating the smell could be coming from outside, and said he would contact the HOA. However, no other solution (such as an air filter) was offered. The smell came and went but remained unpleasant. I was here for a hospital externship, not vacation, so this was not ideal.Three days before checkout, plumbers entered due to a major leak between units. I had just finished a 24-hour hospital shift and had to leave the unit for several hours. The host did not respond to my message about this. When I returned, the issue was still unresolved.Shortly after the plumbers left (saying they would return after I checked out), police knocked on the door regarding a large folder the plumbers had turned in containing sensitive personal information (IDs, Social Security data, etc.). They ran our IDs and informed us that an investigation had been opened. This was extremely concerning, and at that point my boyfriend and I no longer felt safe and had to leave and book another hotel.The front desk staff were very kind and apologetic throughout, but the host never acknowledged or responded to the situation. While the unit itself was updated and nice, the overall experience was stressful, uncomfortable, and concerning.
