Despite an initial problem everything was resolved. And even though Valeria wasn't home, we communicated all the time. Zhu, who was at home, was extremely polite and helpful. The nearest metro station is less than five minutes away and there are many shops close by. It is not in the central tourist area, but it is reasonably close using the metro. As the area is beautiful, I decided to walk to Buckigham Palace, following the Kings Road, which practically goes there. It took me 1:40h and I didn't even notice. The building is not new, but the location is excellent in terms of cost-effectiveness.
