We had a really good time in Castle Rd. The location is great: close to the tube, Camden Market, Regent's Park, and so on. And the house itself was excellent too. We really liked the fact that there were 4 separate bedrooms (and hence plenty of privacy) and the kids were happy with the PS3 and the high-tech TV system (which were quite useful to have given that it rained for most of our stay). I'd definitely recommend the place to others.
