We did not actually meet the host but the apartment had automatic coded locks so there was no problem checking in or out. The apartment was spacious, new and clean, complete with towels and hair dryer. We also left our baggage in the foyer after checking out as our flight was much later, the locks and coded door made it safe and convenient. I believe there isn't any lift, but the apartment is on the first floor so it was manageable. It will take around 25 minutes to get to the old town and around 15 to get to Wencelas square. The nearest underground stop (Nameri mistu) is a 5 minutes walk and is a much more efficient way of getting to and from old town (muzeum station). There is a supermarket in the block across the street and plenty of restaurants around the apartment. The area is far less crowded than the centre but is safe even at night.
