The studio is very cute, but small (as descripted) - perfect for a one to two nights stay in Gamla Stan. It was really clean. The location is great and we could reach everywhere by walking and even the metro station is not far away.
The bed is good if you travel with your partner, but as friends it was a bit small (but cozy ;)). Bring earplugs if you have an easy sleep since the fan is really noisy and we couldn‘t figure out how to turn it off.
Otherwise the place is really quiet, even if it is facing the street.
