Marre and Sophia's place is a great, comfortable apartment with a huge, soft bed (no glorified futons here). It has all the amenities you need for a comfortable stay, but its real value comes from its location: a five minute walk from the Gärdet T station on the red line, which will get you directly to T-Centralen, Gamla Stan, Södermalm, and more or less anywhere else you want to be in less than 20 minutes with no transfers. It's also the closest stop to the ferry terminal. As a base of operations for sightseeing, it can't be beat.
