We loved how close it was to the aquarium! We could get there as soon as it opened and not have too many people around while looking at all the creation. A line was formed way out the door when we finished.
The place has two large bedrooms. 3 of our boys slept in one room and we had a baby with us in our room and there was plenty of space. The bathroom/shower is nice. The kitchen is fine if you are not needing an oven or freezer. It has anything else you would need, and owner is quick in responding if you have a need.
We loved the international food options within walking distance of the place. You probably don't want a car, most places you can get to by foot, metro or train.
