John's sister came to welcome me and brought me even some milk. This place was as described and clean. Internet has some interruptions but that got fixed immediately after I reported the problem.
The apartment is located in a quiet street about 10 minutes by foot from the train station Finsbury Park, where you can choose from a variety of supermarkets, cafes, restaurants and pubs. The neighbourhood is ethnically mixed and if you like African food, you are in the right place.
The Victoria line takes you in less than 15 minutes from Finsbury Park straight to the Centre, the Picadilly line takes a bit longer, but has the direct connection to Heathrow Airport.
You will find everything you need in this small basement flats. John is a caring host and who makes you feel very comfortable at his place. I would come again.
