Staying at Caroline's place had been a wonderful experience and my wife and I had a blast!
Firstly let's talk about location. It's on the Piccadilly line which is super convenient if you are going to town or Leicester square to watch a musical or two.
And the house is a short 5-7 mins walk from Manor House underground and it's a nice and quiet neighborhood. The apartment is on the 5th floor so it actually gets a good bit of wind in the afternoon (when it's hot). The house was very clean and it was super easy for us to do a bit of cooking as well. Stoke Newington street is near her place as well and you can get some nice steaks at a butchery there called Meat Co. That whole street has a lot of good restaurants too.
There was one evening where we got back late and was hungry for some supper and we tried the chicken Doner at Diamond Kebabs near the Manor House underground exit ehich was fantastic. So cheap and so much chicken and chips.
Will strongly recommend this place to anyone who wants to stay in the quieter part of London.
