We enjoyed meeting Sebastian. The neighborhood is almost unrecognizable from when I last saw it 25 years ago. Lots of new, good-looking high rise offices and a young crowd. A taxi driver described the area as the new Silicon Valley but Sebastian's apartment building is a grand old place that has been completely modernized on the inside, close to public transportation and over a Starbuck's for morning coffee. You'll get in shape running up the stairs to his floor and then running up and down the two flights of stairs to the bedrooms on top. I think Sebastian might need to get someone to help him get the spacious apartment ready for new visitors when he has back to back guests. We enjoyed our stay.
