Elsa was a great host. The space is clean, central, and safe. The bathroom and living room were a bit cramped, but manageable for two.
Be sure to confirm whether there is still a construction site next door - it is out of Elsa's control, but the noise did wake us up at 8:30 every morning. Not a problem if you don't need to sleep in!
I recommend Elsa's apartment if you are looking for a charming, convenient location (close to sites and transportation) and knowledgeable, friendly hosts.
