Sofia is an excellent host! We stayed at her apartment for about a month and she really made us feel at home. She offered to pick us up and drop us off at the train station. Her apartment is very spacious, quiet, and comfortable. I slept so well here! We had an issue with the toilet within the first few days and Sofia was able to bring over a plumber rather quickly, even during a holiday. The kitchen is well-equipped but aging (same with the bathroom) — both could use some updating. The washer and WiFi were excellent (very fast internet!).
The apartment is located on a beautiful side street. But if you plan on going out to the center often, beware that it's a long walk (about 30 minutes). Fortunately, the tram station is just a 10-minute walk away. You also have a large grocery store and several cafes and restaurants within a 5- to 10-minute walk. Sofia provides some good recommendations. If you're looking for a quiet, spacious spot away from the tourists, this is a great choice!
