This is a nice, comfortable apartment - 2 rooms, a big, modern bathroom and a tiny kitchenette. The kitchenette is perfectly adequate for tea/coffee and a small meal, but not for serious cooking. Note that the fridge does not have a freezer compartment.
The location is very central and convenient. It's right near the bridge that leads to Gamla Stan (Stockholm Old Town). There is also a subway station nearby.
The building managers, Hedvig and Nicol, are helpful and responsive.
