Highly recommended, we were on our first trip with our newborn son (11 months old) and the flat was perfect for the three of us. Glyn provided us with the basics for the baby (a comfortable and clean cot, a familiar Ikea highchair) as requested by us. Personally I did not mind the absence of a lift since the stairs were wide enough to navigate comfortably.
We also loved the neighborhood, esp the Planet Organic supermarket down the road with long opening hours and the Italian deli for last minute take-away on Cross street.
But most importantly, Glyn is a great host. I locked us out of the flat and he immediately helped us with a set of spare keys. Wouldn't hesitate to recommend him to a friend.
