What neighborhood to stay in BA?


My friend and I are looking at living in BA for a month or two to have some fun and do something different. We can both work from home provided we have internet access so we figured, why not live abroad?

We've been looking into BA a bit, but we are wondering where exactly we should live in the city. Some of our top interests are:
- Good internet access
- A nice place
- Great nightlife (we're both young bachelors)
- Easy to get around

Is there a guide to the various neighborhoods around? Thanks!
