Density is a mixed bag - on the one hand it means your hit critical mass for local services to be viable faster (the good), but you are also usually trapped in a leasehold when you buy (the very bad). You do get a lot of noise in dense houses, and given the "cheapest viable" philosophy that isn't going away - it also means you have to be more mindful of your own noise.
Overall, I don't enjoy it, but it beats driving to work every day.
