Our stay with Nana was really lovely. Nana welcomed us personally and showed us the entire apartment. Our room was cozy including a big comfortable bed. We also had our „own“ bathroom, since Nana said she has a separate one. During our stay we were able to use the kitchen (including oven, microwave, stove, toaster, water kettle and fridge).
We would highly recommend to stay at Nana’s place when in London.
