Constance place is such a great value for money. Excellent location, quiet street, while 5 minutes walking from the tube. You have parks nearby (the heath extensions and Golders, as well as many restaurants and cafes, post office, pharmacy, groceries...). Is very spacious for a London Airbnb, with a big bedroom and a separate room with a sofa bed and a table, both facing a lovely and big garden. I give them 5 stars for that. The one thing you need to be mindful is that the place can be cold, unless the heating is on the whole day (in winter of course).
