This was probably one of the most horrific experiences.
In short, communication at check in was confusing, the building is very worn down, the block is located in a very unattractive part of Brooklyn. There were ants swarming at the entry door, the furniture is falling apart, the mattress was extremely soft, maybe 20 years old, with bedding that scratches you. The place felt dirty and gross.
For us the deal breaker was when we found four rodent traps and three roach traps in the 100SF kitchen. We decided that this space was un sanitary and we could not stay here. We requested a refund and the host was NOT flexible and claimed the rodent traps were strictly precautionary. We have lived in NYC for over 20 years, and know that when you are on a third floor walk up and have rodent traps along with the steel wool and holes around this place --you have a rodent problem.
The worst part of this experience was the hosts refusal to reason and accept responsibility. It was exhausting.
