The building we lived in is an old warehouse, renovated completely. It is quite modern and has all the comforts one could think of. The house is very conveniently located - everything of interest in Antwerp (whether it's MAS, or the Catherdral, or shopping centers etc.) is virtually in a walking distance from it.
Our stay was practically perfect, and we are greatly grateful to Marleen and her husband for the great time we had in Antwerp!
