Visiting London - What's Vauxhall Like These Days

I'll be in Brighton for a conference and then plan to spend 5 nights in London for a holiday. I'll be travelling solo. I'm considering a little B&B in Vauxhall Grove. I lived in London for a couple of years, but that was back in 1989. I had good friends who had a flat in Vauxhall and would visit all the time, often going to the Vauxhall Tavern. As I recall, Vauxhall could be a bit rough back then. What's it like now? I was in my late 30s back then, but am now 70 and can't run as fast as I could back then. 😜
