We had a pleasant stay at Smartments. It's well situated a stones throw away from the main station, as well as surrounded by many restaurants. Getting to the main centre is a 40-minute walk, or can be reached by a tram or train. The front desk staff were helpful and informative. The weekly cleaning was nice, and the lobby area is a nice space to do some laptop work or just chill.
The only gripe we had was the inconsiderate cleaning staff who came into our room on the checkout morning (well before checkout time) while we were still in bed. This happened 3 times on the same morning, with them opening the door without waiting for us to respond to the knock.
