Overall the stay was very good.
The flat in itself is very modern and comfortable, and spacious. Extremely well equipped with all you could possibly need.
The host was open and responsive and took care of little problems we might have.
One thing that may surprise though is that the host will ask you to detail every people you might invite over at the flat, and check his or her passport. Does not really give a feeling of privacy and freedom, and feels a bit ackward. Although overall this thing was forgotten rapidly because the host was nice
The location of the flat is quite close from the center and well deserved by public transportation. But in the same time be aware it's a student neighborhood with a lot of graffiti, and not necessarily the cleanest neighborhood.
