It was very nice to stay at Ulla's near Stockholm (her flat is 5 minutes away from the closest metro station). Ulla was very cool and flexible with me several times. She is really a trustworthy hostess.
Her flat is skillfully divided so that each guest may keep his or her independence. The well-equipped kitchen is a place where everyone can gather and hold interesting conversations in various languages.
In short, I enjoyed my stay very much and would like to be Ulla's guest again whenever I go back to Stockholm.
