This was 100% what I needed while In London. I was here for a ten day trip and wanted to throw a dinner party for my immediate team from around the globe. That would be impossible in a hotel, but in this AirBNB everything was exactly as we needed it and there were plenty of places to shop in immediate vicinity for items I did not otherwise have available.
Dinner went off well and communication was great both before the booking and during - since I needed some appliance help being from outside the UK (stove/oven was great, but I needed some direction on slightly different controls).
While I did not need all the bedroom/bathroom space, it was nice to have available and honestly if I brought my family to London would probably look more to this than a hotel in future.
