I'd highly recommend this wonderful apartment: it's very nicely decorated (beautiful period features as well, such as the beams upstairs). I enjoyed its convenient, central location in the lovely Rivierenbuurt part of Amsterdam, with easy public transport into town, and RAI, Zuid and Amstel train stations are all quite close by for trips further afield.
Marjan was a great host: quick to respond to messages, happy to plan around our check-in / check-out times, and I appreciated the preparations she made to make our stay even more comfortable (fresh flowers, plenty of coffee/tea/candles/toiletries). As mentioned, I can highly recommend staying here if you're visiting Amsterdam!
