Had a wonderfull stay at Tania’s! It’s a good place to explore Brussel from, but due to the big apartment also a nice place to relax and prepare your own food. Walking to the city center takes about 30 minutes, but you’ll walk through either the European district or a shopping street with parks, so nice to do a few times. Ubers are always available and cost about €5-€6. The bus is also available and cost about €4-€5. There are a few you can take. We had a very nice stay and would recommend it!
