Professional, seeking double room

I am a Middle Eastern professional chap aged 35. I am looking for a double room preferably with an en-suite. I’m available to move in from January 2023 and have a budget of £900 pcm with all bills included.

Recently broke up from a long term relationship 12y+. Hence looking for a new place to call home. However, I do have an extremely friendly 12 year old Beagle and would prefer if I could have him with me. But I do understand if that’s not possible as he can stay with my ex.
