This was a very disappointing stay. The apartment was dirty, dusty, and hot. The temperature stayed around 77–78°F all night, yet the only bedding provided was thick comforters, making it impossible to sleep comfortably. When I simply asked for thin bed sheets, the host became argumentative instead of trying to help. They kept saying they were a private owner, as if that somehow excused poor customer service or making guests uncomfortable. It wasn’t until I contacted Expedia that the host responded by providing what I initially asked for. I didn’t want to spend my vacation dealing with unnecessary conflict, so we checked out after the first night instead of staying for the remaining five nights of our six-night reservation. I would not stay here again.
