Pros: Nice room in general, great host as well. Reasonable hospitality with a decent price in London. Easy check-in and out, just that you can't check in before 4pm (host has work) Cons: not very close to central London or attractions (~40min), however, easily for catching an Uber ride. Watch out for a late night walk. No elevator in the building, so brush up your muscle if you have a huge luggage.
Pablo's place is a great value for London. It seems like a slightly lower income area but everyone walking around was very nice. It's about a 10 minute walk to the tube and 40 min walk to a hip area of southern London. The room was small but clean. We were able to lock the door so all of our stuff felt safe.
