The apartment is really well located for a city break in Stockholm, being located on the "Old Town" island of Gamla Stan. The narrow streets and restrictions on traffic mean that generally speaking this is very quite location, despite being in the city centre. The one exception to this was the early morning rubbish collection on Friday mornings.
The apartment was very clean and is pretty much as described in the write up. The description of the kitchen "There is also a small but well planned kitchen. The kitchen is fully equipped with a oven, stove, freezer, fridge, coffee maker, toaster and a kettle." is completely accurate, but doesn't mention that the kitchen floor space is roughly 1 m2 which makes it feel as if you are working in a cupboard. During the five nights we stayed, we successfully cooked a one pan meal on one evening, but this was quite a challenge. However, there are plenty of very good restaurants in easy walking distance from the apartment, and many, many more, a slightly longer distance away in the Ostermalm district.
Charlotta was a great host, providing clear directions to get to the apartment and an easy facility for self check in. We had quick responses to messages, so communication was very easy.
There is easy public transport to the other islands that make up the city of Stockholm, including a direct ferry to the island where many of the main museums are located. Overall an excellent AirBnB.
