Depends on how well you get on with your neighbour and what your internet service is like.<br />- If you're on a limited download service then definitely no, they could kill your service very quickly if they're a downloader.<br />- If you have no limits on downloads then you need to think about speed. If you're on a slow connection then be prepared for it to get slower as you'll probably be online at the same time and if you're both gaming or downloading it's going to hit your speed.
