The comunication prior to travel was friendly and fast. Maike and Caspar are really nice people. The apartment is very easy to get to from the main station in Amsterdam, with buses that go every 15 minutes or so. It's about 15 minutes by bus from the central station, which means it's super quiet, but you're quickly in the city. The noises coming into the apartment are the sounds of waves gently lapping. There's a great bike path along the waterfront to the city, which took about 40 minutes to walk. I don't know how long it would take by bike.
The apartment itself is exactly as described. There's a coffee machine, a microwave, and a small fridge. Also a flat screen tv if you feel like watching the tube instead of exploring amsterdam ( I didn't turn it on).
Maike brought a huge breakfast on my first morning, which was very nice.
All inb all, it is a great place to stay for a visit to Amsterdam.
