In Covid-times, it's always good to have an understanding host who will do a little extra bit to make your stay less stressful, which is definitely the case with Jennifer - she was in constant contact with me regarding the compulsory test kits delivery and, also because of her, all went smoothly. We wanted to spend an extra night because our flights got changed at the last minute, but the flat was booked, unfortunately - I'm absolutely sure that Jennifer wouldn't have a problem with us extending our stay if it was at all possible.
The location is great, walking distance from Westminster and Whitehall and, if you like walking, almost everything else (my most favoured means of transport in central London are the Santander bikes, but can't do that with a stroller, which was the case now).
The flat is nice and welcoming and clean (our only issue was the clogged/very slowly draining bathtub) and feels like a home away from home. When I'm next in London, I'll certainly try to stay there again.
