Leentje's place is simply fantastic. It's centrally located, a stone's throw from restaurants, bars, sightseeing but is also a sea of calm. It's also just 15 minutes from the main station. The terrace is beautiful and lovely to relax and recuperate on after a night out in Amsterdam.
The flat has everything you need and is perfect for a pair. It was also spotless.
If I'm ever back in Amsterdam I'll definitely try to book Leentje's place, although I fear it might be in high demand and already booked!
