Perfect location, close to plenty of restaurants, bars, and walking distance to the major city sites and museums. Would highly recommend hit all of the museums in one day (making use of the €15 pass) and then walk along the boardwalk to get back to the apartment.
The place is spacious, comfortable, and has nice amenities. The walkways are pretty low, so anyone over 6-foot would need to be carful to duck walking through doors.
The hosts were great. Very responsive and on top of everything we needed. They made checking in really easy. The apartment has electronic key entry so no need to keep track of a key during your stay.
