We had a great stay at Hellen's - the studio is spacious, bright, clean and modern and Hellen had gone the extra mile in offering bikes for us to borrow and even leaving a chocolate on the pillows. The studio is very well located (in de Pijp where there are lots of cool restaurants and bars but also v close to central) and Hellen was always very easy to contact. We would definitely recommended Hellen's place!
