The perfect place to visit Stockholm!
Many things have been said but my stay for a long weekend with my wife was too nice not to say a few words myself.
First, Lisa was very friendly and flexible to accommodate us as we arrived quite late in the center of Stockholm. She was very attentive to show us the practical aspects of the apartment and give us tips for sightseeing and good restaurants (see also the famous little guide).
About the apartment, it is really very nice, comfortable and very well located for sightseeing, by walking, and if necessary by public transport.
I strongly recommend Lisa's apartment!
