Monday-Friday, professional, need space for bike

I'm a principal data scientist in a FTSE 100 company with its head office in London, where half my team is in continental Europe, so we work remotely a lot. My family home is outside Banbury in a small village, but I am keen to get a base in London, for mid week, on a Monday to Friday basis.

I am looking for somewhere with secure bike storage, like a garage or bike locker. I'm keen on cycling and my fitness has taken a massive ding during Covid. Mid week I'd be riding a single speed which is never practical to clean, so ends up filthy and you would want stored in dedicated outside storage.

Additionally, I would need a place which is well heated, has a clean kitchen with some storage space for my food, and a decent shower. Would prefer if my room is not used at the weekends.

My budget is a constraint, not an objective, so please don't contact me if you need more than this amount!
