We spent five days at Sjoerd & Nanna's flat, which is located near Vondelpark and Leidseplein. The flat is decorated with a lot of character and contains many vintage-style items. There is a kitchen which you can use the cutlery/crockery/fridge, a lounge area with a sound system you can use to plug in an iPod, a large bathroom and a bedroom. There is even a little "balcony" area to sit outside overlooking the courtyards and have a beer in the sun. A selection of toiletries, fresh towels, clean bedding and some snacks were there for us as a welcome pack, along with a handy printed information sheet. Communication was quick and informative and staying in the flat made the stay in Amsterdam very comfortable. There are some steep stairs to get to the flat but there are definitely steeper ones elsewhere in Amsterdam! We'd highly recommend staying here.
