Sarah's place is like it is pictured. We had 3 adults and plenty of room. The apartment is cute and clean with amenities for cooking. The bathroom is functional but with a tiny sink. We used the kitchen sink more often. The bed and couch were comfortable but few places to unpack. The apartment was spacious enough to lay out suitcases on the floor.
The location is perfect for the local experience. There are a few small grocery stores near by but most sights you will need to walk a ways to. There are lakes 5 blocks away which is a nice area to walk around.
The train station is about a 13 minute walk with the Little Mermaid another 10 minutes after that.
We arrived at night which made finding the apartment and getting the key more challenging. I would recommend arriving in daylight hours. Everyone we met in the building was very kind and spoke English which was helpful.
