Oh my goodness--what a great stay! The apartment was in a PERFECT location to walk everywhere in Amsterdam. We only Ubered to and from the airport and walked everywhere else. There is a cute square literally in the backyard of the apartment (Rembrandt Square--I think) and was perfect for a nightcap at the end of a long day of walking. There were other bars and cafes on the same street as the apartment that are convenient.
Raul was incredible and met us right at the front door of the apartment. Raul has done a great job of making the apartment versatile if you're treating it simply as a place to crash or someplace to hangout. The decorating touches, Bluetooth speaker, full kitchen set-up and multiple hangout nooks made the place feel immediately like home. The garden-apartment style of the place makes you feel a part of the city but still VERY safe. The convenience and central location of the apartment does mean you get have some road noise late into the night and early in the morning. This wasn't a huge deal since we luckily remembered to bring earplugs on our trip. I would suggest you do the same.
Everyone in our four-person, two-couple troupe agreed that we'd stay at Raul's apt. again in a heartbeat if we returned to Amsterdam. It surpassed our expectations!
