This apartment right in the middle of Gamla Stan, is wonderful! close to the metro and central station, close to the shopping streets of Norrmalm, close to Slussen/Sodermalm... The apartment is really cosy, good for 4 people, easy to reach and easy checkin (if you follow the dealer rules). It has a kitchen with enough utensils and other kitchenware. Bathroom is quite small but fine. The dining/living room is really confortable (sofa-bed is comfortable). And finally the double bed room is also cozy.
We felt like a privilege staying there...and defenitely would stay there in the future.
On the other hand, cleanning could be better (even though it was not dirty either).
Before getting to the place, the host will send you one million comunications with the million rules...you'll feel a little overwhelmed but if you read what they say, it's only common sense stuff, so it is not too bad.
We did not like you can not check in until 17h unless you pay for more money.
And the worst thing (even though it was not too bad) is that from thursday to saturday you can hear the music of the pub around the corner, even though our stay was in january and windows were closed. The pub closed soon those days (around 23.30h). I would recommend the property to complain about this situation to the municipality.
But even these not-as-good things, we had an excellent stay in there!
