I only spoke to Sonja in person briefly when I arrived, but her hospitality was appreciated (snacks and water left in the room, plus plenty of tea and coffee to choose from) and the room was big, bright, and a pleasure to stay in. I arrived from the airport and left by train, and the S and U stops made access to both, and to all of my sightseeing, super easy. I also really liked the neighborhood, as it was quiet in the evenings, but also offered everything I needed - grocery stores, coffee shops, pharmacy, etc. I would definitely recommend Sonja's place.
