Our stay at the AirBnB of Catherine and Charles has been simply fantastic. They are the kindest, open people and made sure our days in London were great. The way they use AirBnB, is what we think the concept is meant for - meaning that if you want, it can offer more than just a place to stay. For us, it led to lovely get to getters with good and fun conversations. I can imagine that not everyone is interested in this, which is no problem because they are respectful hosts with no intention to spend time with people who prefer not to.
Further, the place is located in a nice and calm neighbourhood, close to the metro line (bringing you in no time to the city center). Perhaps more importantly, the AirBnB is near Hampstead Heath - absolutely breath taking views (skyline London) are literally around the corner. The place is very clean, beautifully decorated and makes you feel at home straight away.
