Calypso is the place to stay when being in Rotterdam.
Apartment is perfectly located in city center and offers a lot of amenities to relax after work and/or having enjoyed the city for sightseeing, shopping or at night. Personally, I really enjoyed the free use of the in-house gym and the possibility of parking in the building.
Mesut was super-responsive in his communication prior or during our stay.
Special thanks to Sidar, the co-host, for check-in and -out, as well as being very attentive in resolving smaller issues or special wishes.
