The small apartment is in a very safe and quiet neighbourhood, so you can sleep and relax there very well without any noise at night. The apartment itself is comfortable (especially the beds!!!) and has everthing you need, although especially the kitchen could have been a little bit cleaner. You have a lot of supermarkets, bakerys and Cafés around and you can reach the centre easily by train.
Adri is a very nice and helpful host and I got even picked up at the airport by her husband the evening I arrived. As they live in a flat in the same house, there is always someone around in case you have any problem with the apartment.
If you're looking for a nice, quiet and affordable place on you're own, I can definetly recommend staying with Adri!
