I stayed at Andrea and Tiana's during the days I was searching for renting an appartment of my own in Brussels for long term. The flat looks exactly like in the pictures. It's very cosy and nice. The heating works perfectly, it was nice and warm all the time. Everything is clean and prepared in detail for your comfort. You even have bathrobes!
The only disadvantage is the tram that passes right in front of the building. I am not at all a light sleeper and even so especially early in the morning it was a bit uncomfortable to hear it so loud. Another (very girly, I know) issue that I had was that there is only one mirror in the flat, the one from the bathroom. :D
Communication with Tiana was flawless.
