I really enjoyed the stay in Marco's nice and lightful appartment. The key hand-over was very easy thanks to a key locker I was able to open myself. I tried to get a flat to very last minute and Marco was very helpful and flexible to support me. His documentation & FAQs about the flat is perfect. The location is not really downtown but the tube is a few meters away and get you quickly into the center or to the Excel exhibition center. Definitely a spot to recommend.
