I'll be headed to work from Watford for about 3 weeks. I'm a 30s single male and would be looking for fun things to do after work. Is Watford a complete sleepy town? Is it walkable and easy to get around in? Or should I perhaps consider staying somewhere in London? I'm gathering that it's a 20 minute train ride from Euston to Watford. I just don't want to be stuck in my hotel room for 3 weeks after work with almost nothing to do. Any advice is appreciated!
