If you find this Airbnb available, I'd strongly recommend that you snatch it. The location is perfectly situated just a few minutes from Tower Bridge. If you're not familiar with London geography (as I was before I visited) then rest assured this flat is no more than an hour's walk from almost any place you'd want to visit in central London (Tower Bridge, London Bridge, St. Paul's Cathedral, the Tate, Westminster, etc... etc... etc...). But you don't even need to leave Bermondsey to have a lovely time, as there are several lively streets with restaurants, stores, and even a few museums to visit. You can easily spend a good day or two just walking around the local neighborhood.
As far as the unit is concerned, it is well decorated and furnished, with a full kitchen and large bathroom. It has a washing machine and several drying racks to keep your clothes clean so you can pack a lighter suitcase. The blackout curtains are probably the unsung hero of this place for me - it's rare that Airbnbs have them. It's been more times than I could count that a unit had either no blinds at all, or just those very thin lace blinds that are so popular. Here, have no worries, the sun will be blocked out so long as you wish, allowing you to overcome jetlag easier and adjust to the local time.
Frank is a kind and responsive host and made staying at his place easy and enjoyable. He was very accommodating.
