Provided a good, well priced base near to the Jubilee line at Willesden Green and with good bus links, in particular the 52 Victoria bus which goes by Portobello Road and the Natural History Museum, Science Museum, and V&A amongst other places of interest. If you are driving there is free on street parking over the weekend provided you can find a space (we did), and there is some local cheap parking via JustPark or similar for weekdays, though I think Reuven can also help with weekday parking. The place was clean and warm, with a decent shower. Don't be afraid of using a bit of muscle to get the fold-away beds sorted. Everything you might need is in walking distance, with various places for breakfast on the way to the station. Very easy place to get to if coming down the M1. Recommended.
