Location is very good, with easy transportation possibilities to anywhere in town. Bus stops and train stops are really close. Plenty of restaurants and bars, supermarket closeby, so highly recommended for this. The appartment is auite small, but ideal for 1 or 2 persons if you're looking for a room to spend the night with some kitchen equipment.
Downsides: Collecting the keys is a 10 minute walk. Not a big problem, but if you're carrying some luggage something to keep in mind. Biggest downside is the lack of cleaning, just passing with a vacuum cleaner isn't sufficient. Plenty of dust in the appartment, kitchen eauipment (pots and pans) are just disgusting, blinds are partially broken down,...
Overall it's a good stay for the money, but it needs to make some adjustments to the apartment and (based on other reviews as well) hire someone to do a decent cleaning when previous guests leave.
