The apartment is in a quiet street, at the 3rd floor ( for us it was not a problem at all but there is no lift for information). City center is a walk of +-25 minutes, depends where you're going. We went there for the new year, fireworks on the Erasmus bridge were really nice. You can park in the street. Uber is really easy to go in the city center if you don't want to walk. We didn't took the public transport but it's in the next street. Marnix was a great host and flexible, he went with us to show where to pay the parking and was there for all our questions before.
