It's hard to know where the truth lies. I am allergic to perfumes, like air fresheners. When I contacted LSA, they told me they heard my request about fragrances. Before I actually booked the flat, I requested that LSA confirm that the flat did not use air fresheners. In an email (January 20), the LSA agent confirmed that the flat did not use air fresheners or perfumes. When I arrived at the flat (January 28), the unit smelled strongly of perfumes. The leasing agent (not from LSA) told me that the air fresheners had been removed before my arrival and that the windows were left open to help air the place out. It is possible that the leasing company does not routinely use air fresheners. It is possible that the leasing agent indeed told LSA that the units do not use perfume. It is possible that a prior tenant purchased the perfume devices and left them in the apartment after vacating. It is difficult to tell what actually happened. In the future, I intend to deal directly with property managers so that I can have a more direct and accurate line of information.
