Looking for room to rent

I'm looking for a room to rent for at least 6 months. I have just moved back to England from Madrid and I'm looking to move out there long term but it's not confirmed whether that will happen or not yet.

Currently working as a software engineer at a sustainability company in central. I was commuting in from my family home just outside London but it's been a bit of a nightmare to see my friends so I'm hoping to be able to move to London to make that easier.

I'm half dutch, half turkish and grew up in England. Let me know if you have any questions!
