I highly recommend this apartment. It is clean, stylish, warm, inviting, safe, and in a great location. I worked at NATO for six weeks and stayed in Nadia's place. There is public transportation around the corner. It is very convenient and close to anything you could want. Restaurants, bars, food shopping are all within walking distance. But if you want more, simply hop on the 55 tram, which is one block away, and you can easily get to the rest of Brussels.
When I walked into the place, for the first time, I was blown away. It looks like the pictures, but so much better. It is secure, and safe. There is a workshop below the apartment, but as long as you don't expect to sleep all day, it is not a problem. I recommend this place emphatically and will return in a year when I come back to NATO. Thanks Nadia!
