We stayed 4 nights at Marks place and we found a flat that suited us perfectly. Quiet at night, the kids slept very well on the comfy sofa bed, the kitchen was well equipped, a good working shower, DVDs for the evening and everything perfectly clean. The flat is not too far from the center, so we mostly used the bus to go around. Just over the main road there is the Grand Union Canal where a pleasant walk takes you to little Venice.
We will be back soon
