We had a great time in Stockholm! Kristina is a very sweet host and has a lovely apartment situated in the middle of Östermalm. There are amazing restaurants just around the corner. Discover Stockholm is doable by foot, but it is also possible to travel easily by metro since the apartment is really close to a metro station. Communication with Kristina was good. She was flexible with serving breakfast at different times and responded to our messages within half an hour.
Would definitely recommend!
