The apartment is big enough for a larger party: the only minus points are that there is but one shower, and that beds are 140 wide (not very comfy for two adults).
The location is great, near the port, with the centre, key sights and airport easily accessible via public transport. It's a safe area, with facilities (supermarket, pharmacy, restaurants, playgrounds) nearby. We stayed with a small child and it worked out satisfactorily.
The owner reacted very quickly to issues (e.g. the microwave didn't work and he substituted it immediately; the floors were not very clean and he made sure that it got a washing the same day). However, we did have to do some cleaning in the kitchen (fridge, crokery). Some of the pots were not working on the induction stove and some were in a bad condition/ shape... Some of the windows couldn't be closed, others were blocked, the showerhead was leaking during showering. Nothing serious, but the apartment gave a bit of a "cheap" feeling.
