Tim's flat was the perfect temporary home. I stayed for a month and lived very comfortably. The large windows offer generous sunlight into the bedroom and dining room, the kitchen is well stocked, and the bathroom is spacious with good water pressure. Tim was very responsive and kindly agreed to shorten my stay by two nights.
The city is highly accessible as the flat is only a couple minutes walk to two Tube stops. I didn't find that much to do in the immediate West Kensington area but that shouldn't stop you.
