Eva has been a great host. Her home is beaufiful, cozy and will make you feel warm after a day walking around Stockholm. Definitely recommend her place for a short - midterm stay just like her description says (vacation only).
Location is good but bear in mind it's a bit far from the centre. Metro station (tunnelbana) is only a minute away and the line 18 will take you to Gamla Stan in 20 minutes. I recommend you get the SL all access card and then you can easily move around the many islands.
Stay at Eva's, you'll have a good sleep and replenish your energy, make sure you follow the rules and enjoy Stockholm!
Thanks Eva!
