Location, location, location!!! Right in the middle of Gamla Stan (Old Town), walking distance to all main attractions and surrounded by excellent restaurants and lovely shops.
The apartment is fantastic, spotlessly clean and much bigger than it looks in the pictures. It is also very quiet and secure.
The girls who met us were very helpful (staying late to meet us due to our delayed flight) and also booked taxis when we asked.
i would definitely recommend this as the place to stay for any couples visiting Stockholm.
