Naz's Airbnb took the stress out of a busy work week I had in Kew. The no-frills room was quiet and in a very safe area with the closest train just 2 minutes away. The Wi-Fi is excellent. I 100% recommend if you need to be in the area for work and just want a place to sleep/shower.
BONUS: The room is over an Indian takeaway operated by Naz with some of the best food I've ever had. I'd go back to Kew just to try it again. I ate there 4-out-of-6 nights and it still wasn't enough.
