I thoroughly enjoyed my week-long vacation stay at Simon's place. The communication with Simon was quick and smooth. Finding keys and checking in was also very easy. Simon's directions were spot-on. The Underground station is a short 8 min walk away and it takes you directly to central london in about 25 mins. The location was very good with some coffee shops, local grocery stores and other smaller stores.
The kitchen is tiny but useable. All the required pots and pans are available for a quick lunch etc. The only appliance missing is a microwave. I am sure Simon would have happily provided one had I asked for it. The laundry machine came in handy for me on the trip.
The bed was very comfortable. If you have more than one international size suitcase, things can get a little tight. The bathroom was clean, with the regular necessities.
Overall, this would be a good place to locate yourself if you are traveling in London.
