We stayed at Richard's flat for a week in July. Check in and check out were extremely easy, thanks to a lockbox by the front door of the building. The flat is within a 10 minute walk of 3 tube stops on 2 underground lines, both of which can get you quickly to the center of London. It's also a quick walk to Primrose Hill park and Regent's Park, my favorite in all of London. The neighborhood is lovely and peaceful, and there's a Tesco Express and a Starbucks and other necessities 60 seconds away. The flat itself is a comfortable size, with a large kitchen (as London flats go) with a separate washing machine and dryer, and benefits from having windows/ sliding glass doors on 3 sides, which makes it quick and easy to keep the flat at a comfortable temperature. The lounge and the smaller of the two bedrooms have sliding glass doors onto a south facing veranda overlooking the gardens below and the lights of London farther beyond. (These rooms get the morning light, which starts very early in the summer, so if you have a harder time sleeping in a light room, you may want to choose the other bedroom.) There is a large flat screen TV in the lounge with hundreds of channels, the beds were comfortable, and plenty of towels and pillows were provided. Both Richard and his local host were very responsive in communications.
