We were a group of 15 and we were looking for a one single big flat to stay all together and I would say that Marco's flat was the perfect one! We had 16 good beds available in the flat and were able to all seat and eat around the same table in the leaving room. The flat do have everything needed (towels, bed linen, etc.) and near to tramway stations.
Last but not least, her assistant Bibi was really nice too!
I strongly recommend Marco's flat!
