We had a really, really nice stay at Alex and Nik's place. Even though the rest of the world went sideways (coronavirus-wise) about 4 days after we arrived, we felt welcome and cared after for our entire stay. Additionally, Kay (who lives in the other room) is an amazing hostess and has been extremely hospitable towards us.
The flat is spacious, and floor-to-ceiling windows face towards the sun all day! It is near some canals and parks, which have been our saving grace in these trying times. Getting fresh air—away from traffic and roads—is as simple as it gets in this city :) We'll absolutely stay here again the next time we're in London—hopefully under better circumstances next time!
