In an excellent spot in the heart of Rotterdam, cozy little appartment in a lively street. The bars can be noisy on Friday and Saturday night (earplugs are thoughtfully provided), so if that could bother you my suggestion would be to rent one of Fatima's other apartments in the same building, as they have less problems with this (we've stayed there as well).
The place itself is very clean and cozy, and with thoughtful little details (like the candy!). Communication with Fatima is quick and clear, which made check-in a breeze.
Highly recommended.
