Lovely quiet area, gorgeous flat (small but so cleverly designed, perfect for a short break) and so accessible by public transport or bike to central Amsterdam. We loved using the bikes!
It's also well worth following their recommendations for local places to visit/dine, the Dam Boat Guys were great.
We went in early September, but the weather was so pleasant I went for a great morning swim! However we weren't prepared for the mosquitos so be wary of leaving windows open overnight.
Overall a fantastic stay, the hosts are so friendly and helpful, I'd love to stay again in future.
