There were some troubles with the wifi and the keys when we arrived but both were fixed very quickly by Maria Cecilia and her husband who truly made us feel welcome and comfortable during our stay. The communication was smooth and quick and there were no troubles during the rest of our stay. The apartment was clean and pretty, a good sized space for two people. We had all the kitchen appliances we needed for our stay, so if you intend to cook like we did, it is made as easy as possible. The apartment is located relatively close to the city center and more importantly, it offers you an extremely simple and easy route to the center of Brussels. Once you know the way by heart it should take about 15-30 minutes to walk there. There's also plenty of grocery stores and restaurants near the place so we didn't need to walk far to get food. We didn't use the bus much but the Luxembourg bus station that has excellent connections to the airport and the train station is very close to the apartment which was very helpful to us as our luggage was quite heavy to carry.
