We enjoyed our stay at Tim's place. The studio partner is located on the second floor (with elevator access) fronting the bustling area of Edgeware Rd; where the activity continues well into the night.
On check-in, my wife and I arrived at Paddington Station from the airport and walked to the apartment (approx 15mins) - in hindsight we should've just taken a taxi for the convenience as it was a hot day and we were lugging around some heavy bags. Note, Marble Arch and Edgeware Road tube stations are much closer to the apartment (approx. 5-10mins walking distance), very convenient!
Tim was away on holiday when we arrived and had his housekeeper welcome us to the apartment. The introduction of the place was very brief (5mins) and we had to figure out a few things on our own. The TV wasn't working when we arrived, so we contacted Tim who was very helpful - he checked with building management and got the antenna fixed.
The apartment was clean and tidy with spare linen in the cupboard, we stayed here for 9 nights so this came in handy. Edgeware Road can get quite noisy at night, if you are looking for a quiet place to sleep, this may not be the place.
