We had a good stay in London, in this simple apartment, with enough space for 4 and a good location (south of shoreditch).
We made some suggestions for improvements (cleaner or newer bathroom, better bed, better equiped kitchen). The shower can only be managed if you are tall enough, our kids couldn't.
Neighbours were loud 2 moments a day (late in evening and in early morning).
Cumminication with Tanvir went good. We could arrive earlier and could have left our lugage with Tanvir if needed/wanted .
