A couple of weeks stay

I am a calm Ukrainian guy, coming to Borehamwood, to spend time with my son , who lives with my ex-wife at Bristol house, Eldon Avenue. Looking for a place to stay, mostly just to sleep at night, as close to my boys address as possible. Because every morning I’ll be walking him to school from his mother’s place. I know that my budget isn’t high, but l am a zero problem man and I will be spending most of my remaining time outside of my accommodation, going to the Central London by rail , visiting friends and places. No parking needed.
