Underground parking space – costs and benefits

Hello forum! I ask myself a question again and I really don’t know what to do: at the beginning of October I get my new used car, approx. 20,000€ and compact class. It should be well maintained and driven for the next 5-8 years. My landlord has now asked if I would not be interested in an underground parking space. This would cost 50€ mtl. and is located directly at the house. Access only with key card. My question: Is it worth it? Are there serious disadvantages of a underground parking space atzes? Is the price too high? Etc… My new one has a disc heating and also heated mirror. So the winter should not be a big problem. At the sea with plenty of salt in the air I don’t live either. Does someone possibly have more life experience with it and want to share it with me? I would be very grateful about it.
