Silvia's apartment was very comfortable and sparkling clean. We spent more than 2 weeks there and found everything we needed for 'regular living' there (I would point out excellent Wi-Fi speed which was important for our work).
Since the two of us like to walk, apartent's location was convenient for us since it took us around 30 minutes to get to the city center though there were metro stations near the apartment, too.
Finally, Silvia was great host - proactively provided recommendations, made sure there were 'welcome gifts' and was always available for our questions/issues.
