The flat was great for our family of 4. We loved the location, which is just a short walk to a convenient tube stop as well as close to popular Upper street (lots of shops and restaurants). Yen's place is clean, the kitchen is stocked with everything you need, and the bathtub is lovely! Our kids slept on the fold out sofa and extra sofa which were both comfortable. The main room has high ceilings while the bedroom has lower ceilings but that worked fine for sleeping!
Yen and her friend Alex were super helpful prior to arrival and during check-in. Wifi works great as well. We really enjoyed our stay.
