When searching for an apartment, especially in a city like Toronto, hygiene can be a deal-breaker. From my experience, spotting grime such as mold or mildew in the shower grout or behind the sink is critical. These can indicate poor maintenance or underlying moisture problems that might lead to health risks or costly repairs down the line. It's important to understand that grout, while prone to staining and wear, should be regularly cleaned and replaced if needed. If an apartment has visible buildup or odors, it might hint that the landlord neglects upkeep, which can be problematic. Even if the rest of the unit seems appealing, these signs should not be overlooked. I recall one unit with a small den near the entrance, enclosed by mostly solid walls, which I found more acceptable than curtains dividing rooms. However, the hygiene issues were enough for me to pass on it despite its location and price. For prospective renters, I'd recommend taking a close look at all moisture-prone areas and smelling for any musty odors. Don't hesitate to ask about recent renovations or maintenance work on bathrooms and kitchens. These precautions can save you from future headaches and ensure you enjoy a safe, healthy living space.
