I don't have anything to complain about, the place was very nice.
The hosts were very nice and helpful. I had a quite busy schedule and they were able to advice which bus to take to get where I wanted. That really saved me some precious time since I'm not the fastest googler.
The room was perfect. Bed is comfortable, colours are relaxing and the whole room just made me wish I had more time to spend in there.
There's so much to see just a little walk away. Big Ben, London Eye, museums, etc.
Oh and I almost forgot! Wifi in the house which is very useful if you have a data limit abroad and need to check some things online!
