Enjoyed a lovely stay at Kerstin's home. The host is really lovely and her home is just as nice.
The location is perfect if you want all the joys of being in camden, but none of the noise of drunken revellers when you close your door. The home feels warm and inviting, and was great for our two week stay.
The only thing I would mention is that the garden has astro turf, so if you are bringing your pup you'll need to walk it round the block a few times, but it is a very nice block to walk, regents park is only a few minute walk and the hosts are very nice about assuring you that your dog can use the garden in the night and for emergencies and such. Also, the stairs that she mentions are tight, but there is a back route, so as long as one of your party is a size 14 or below you should get on fine.
Overall, we'd stay here again, my dog was so comfortable in Kerstins home, as were me and my wife. The perfect place to stay if you have to be in Camden for a few days.
