I had a great time at Joanna's apartment.
The apartment is very sweet and cozy. Joanna was very welcoming, I felt comfortable and at home.
The bedroom is in good size, perfectly fitting all of my stuff, with a hanging rack for clothes, and a small desk. the bed was really comfortable - i had a perfect sleep.
Islington is a lovely neighborhood, very nice and quiet but with high street is just around the corner from the apartment, with a lot of restaurants, cafés and shops.
Two Tube stations are a short 5-10 minutes' walk, with which you can get to basically anywhere in town.
Would definitely recommend this room to anyone who is looking for a great stay in London.
