Brussels is a low-emission zone (LEZ) since the beginning of 2018. Foreign visitors wanting to avoid a fine, must register online. This is compulsory for all foreign vehicles, also if your car meets the standards. Register on https://irisbox.irisnet.be/LEZ
You have to pay for parking at the payment terminal outside before you leave.
When taking a taxi, make sure you specify you need to go to UZ Brussel in Jette. There are a number of other hospitals and fertility centres in Brussels, which are better known than the CRG to many French-speaking taxi drivers.
