We stayed for a week and Matti was really kind and helpful and responded quickly to all our questions. Everything was working great, but there was a minor problem with the locks to the building, but we finally got it after trying every possible way to turn the key on the lock for 15 minutes. Anyway, Matti has really good taste and the place is beautiful. Lavapies as a neighborhood was probably not the most quiet, but still very nice with good restaurants, big 24h grocery store near by and a huge park in a walking distance. 5/5 recommend!
