To quote my 16 year old son, Joakim's apartment was exactly right for us. It was exactly as described, very clean and functional and gave us great flexibility for our visit to London - between getting out amongst the sights of London over new year and being able to take it easy, in comfortable surrounds.
Joakim went above and beyond what anyone could have expected in handling some difficulties we had prior to arrival in London (we got snowed in Sapporo and delayed by 2 days), all while being overseas himself. He was responsive and found solutions for the issues we faced, reducing the stress created by the weather delays.
I would recommend Joakim's place to any small party of 3-4 people looking for a convenient base from which to explore London.
