Everything spot on to description. People living there are super friendly and welcoming. We were not made to feel like an inconvenience at all. House lovely. Cosy homely vibe. Incredibly warm. Clean. Towels provided, lots of hangers etc... comfy bed and duvet.
Only tiny negatives worth considering are...
1) tube can be heard in the bedroom rumbling underground throughout the night (fell asleep after an hour or so though so it wasn't too bad and not sure what time it stopped).
2) shared bathroom with other guest room and it seems also the house inhabitants, so had to wait a few times in the morning to use it.
3) you cannot lock your room when you leave it.
One other thing to note but not a negative - you need to be able bodied to get down the metal stairs outside with your luggage as they're quite steep/slippery in the rain. But absolutely fine if you're healthy.
