We would defintiely recommend staying at Sam's place. It is really well equipped - food essentials left (fruit, milk, biscuits, tea, coffee), bathroom items (shampoo, conditioner, shower gel), even an umbrella in case you're visting in the summer! The place was spotlessly clean when we arrived and check-in was straightforward. Daily permit parking (£4 per day) is available on surrounding streets. Location is very quiet, but also very close to underground, shops and good restaurants and cafes.
