The location of this apartment is incredible, on one of the narrow streets in the old town. Be aware that access requires ascending a spiral staircase, which is fairly short but there is no lift in the building. Everything in the listing is entirely accurate and the photographs depict the apartment very well. There is plenty of space in the communal areas with reasonable-sized bedrooms. The apartment was perfectly clean on arrival. One bedroom had no windows and nothing inside it at all other than the bed, which is worth keeping in mind if you like sunlight in the morning. Bathrooms were good, with very powerful showers.
One very minor issue is that the TV was unusable due to its inability to connect to the Wi-Fi. We tried a few things which didn't resolve it, but I'm sure an IT expert could probably have fixed it.
Overall, extremely happy with the stay and would book again if ever in Stockholm.
