As mentioned in other reviews the apartment isn't exactly quiet. The trams right in front of the window (which only stops between 01:00 and 06:00 or so) and the sound of pedestrians and cars, and the steps and voices of upstairs neighbours make for a challenging sleep. This should be mentioned in the description as you can't expect a guest to plough through all the reviews to discover what to expect.
Also the reviews from months ago mention the state of maintenance and cleanliness that was unchanged when we arrived: fungus and moisture stains on walls in kitchen, bathroom and toilet. The bed was indeed missing the middle mattress to make it a complete boxspring, so it was noisy and bumpy. The shower drain being clogged with lots of hair was the finishing touch.
Via chat Amaryllis promised to improve on these things as soon as the apartment is unavailable, so maybe we'll return when that is done.
Despite the shortcomings we had a decent stay. The location was excellent, the parking in the street nearby was affordable (€6/day) and the restaurants around the corner are great!
