I wad staying with Hilda for the last three months. In all this time I never felt like I might have chosen the wrong host or location.
The place is clean and everything you need is provided for. Everything is nicely decorated like you can see in the photos. One minor nit is the WiFi which wasn't particular strong in my room. (Works for mail and text but for Skype, video conferencing or working from home you should probably go into the living room or kitchen)
Hildas place is about 5-10 minutes from Kentish Town Station from where you can get to the city center within 10-15 minutes.
The house is not next to the main road making it a quiet place. During the day you can usually hear some kids playing outside.
Apart from that I had many nice chats with Hilda. She can provide you with many great tips of what to do in London and how to get around - just ask.
Hilda even invited me to dinner with a couple of her friends once!
All in all, this was one of the best Airbnb experiences I had so far.
