We did have some challenges with the rental ,air was broken down in bedroom for first 5 days , then they did replace the unit and was great after that. Same scenario with the main TV although it did work well he last week or so. It is a nice little complex with friendly people. The mattress needs to be replaced no question on that as it must have been the original. Unit was not very clean when we arrived floors and bathroom were OK but light switches and things like that were black. Yes we cleaned them. With new mattress could be comfortable unit . Also could use an exterminator once in a while as they have an ant problem.
