I stayed at See Me Spring on Soi 10 in early 2019 before covid hit. Its not super close to walking street, but close enough. IIRC, It's a 10-15 minute walk along beach road. The problem is its hot as shit so you might be all sweaty by the time you get there. However there are interesting things to check out on pretty much every soi along the beach road area so you don't necessarily need to be right next to walking street. Also, there's always the baht buses which you can hop on and hop off of for like 50cents or whatever they're charging now which runs the length of beach road.
See Me Spring was perfectly fine imo. Not super fancy but definitely not run down. I had no problem inviting guests to my room.
I suggest checking Agoda or other some of the more Thailand/Asia focused forums for more info. Good luck!
