Other than 'possible' leaks - which can happen in any slide, you'd also want to be aware of condensation. Slides are not insulated and if the door is closed humidity or cold air will occur and you'll have a possible mold problem. A bedroom generates a lot of humidity just by your breathing and also with the bathroom being close. Personally, we would stay away from the wardrobe in the slide.
