Excellent location, a minute walk to the river and a few minutes walk to get to the historical city center. The apartment itself is fine but a little strange. The ceilings in the kitchen and bathroom are extremely low and the living area have no windows. The bed is also a little uncomfortable. But otherwise, it's a fine place to stay if you mostly care about location, and especially given the price.
Heads up, there's no air conditioning. However I stayed there on an extremely hot weekend and inside the apartment fortunately didn't get too warm.
