Paul and Anja were waiting for me at the apartment even though I was an hour late due to flights. They are very friendly people who made me feel very welcome.
The building is currently undergoing repairs, but this did not affect our stay at all and in particular the place was totally quiet at night.
The apartment looks newly remodeled, is very nicely furnished, immaculately clearm there were plenty of towels and supplies, they had bought fresh milk for me after asking if I wanted some (!) and I think the living room looks actually even better than the photo.
There are buses nearby, walking to the Thames bank (e.g., the London Eye) is not too far, and the E&C tube station is 5 minutes away.
It was a pleasure to stay at Paul's and Anja's place and I will do it again if I have a chance.
