Exactly as in the pictures. Clean, commercially-rented apartment in a wonderful location. Very close to the underground, walking distance from the shops/market at Portobello road, restaurants, etc. Was a very good value for money (in mid-Jan, which is not high season), and the host was very responsive when I had a minor issue with the plumbing.
Unlike many AirBnBs I have stayed at in London, this is a commercial space, not someone's home that they are renting while they are away. So, on one hand, it wasn't the coziest place I've ever stayed, but it also means that you don't have to fret about accidentally breaking someone's possessions, etc. Would probably be especially lovely in the spring or summer if the weather were warm and you could make good use of the balcony.
