Our family of four (two teenagers) spent a week in this airbnb while we explored London. It was great to have three bedrooms and a kitchen and be able to walk everywhere. The living space in this unit is a bit small so we spent most of our time out and about. The unit is close to Portobello Road and to some great breakfast spots. We walked everywhere from there - most attractions in London are about 2-4 miles away so we walked a lot but it was really fun to explore (and the Lime bikes were great too!).
The beds in the unit are firm and comfortable and we had enough linens/towels. Access to the unit was easy and communication with Penthouse Stays was easy through the messaging app. There was some construction behind the unit on the weekdays that started around 8am every day and regular city street noise at the front of the building most mornings so we were generally out early.
overall, this unit is great and was a nice home base for us during four week. Highly recommend!
