The location is totally perfect for a tourist, it's easy to reach all the interesting areas. Yes there are many stairs but they're not a problem if you're reasonably fit. It is a clean, quiet and secure apartment block.
The apartment was clean, comfortable and looks just like the pictures. It is very well equipped for self catering. The living area and kitchen area experience some noise from the street but the bedroom is quiet. You cannot see much of the outside world when you are sitting down inside but there are good views from the small balconies / windows where you can see the major landmarks.
The bed is comfortable and we slept well.
Nuno was a friendly and welcoming host easy to communicate with.
