This really is a great place to stay!
The apartment is exactly as described and shown on the pictures. Looking out onto the water and the occassional boat passing by is really nice and relaxing.
There was a bunch of fresh flowers in the living room, the refigerator was well stocked with beverages and breakfast essentials were available. Anything else we needed could be bought at the shops about 500 m away.
For this, and for going into Amsterdam the bikes were really convenient. It takes around 25 minutes into the city; basically the entire way is on bike paths, the last third goes through the Vondelpark - so quite a nice ride.
Frans was a really nice host, explained everything we needed to know, even printed some museum tickets for us.
If we ever return to Amsterdam, this would definitely be the place to stay!
