This house is a real gem. An idiosyncratic 1920s dwelling by a well known architect, it has been sensibly, and lovingly, updated with modern bathrooms kitchen etc. We would happily go there again, and I have already recommended it to friends.
One thing to note is that the climb 5 floors from kitchen to terrace is steep. My 89 year old sister managed remarkably well, but if one of your party has restricted mobility, or is very unfit, you may wish to think carefully before choosing.
