The apartment was spacious with access to many attractive places. However, the loud noise from the restaurant Casa Carmen below was excessively loud past 01:00 hours. Another negative was that we tried to call the apartment's after-hours emergency contact at least six times between 22:00 and 23:00, and no one answered the call. So why provide the number if no one will answer? Lastly, they offer early check-in and late check-out for low cost €. I did the early check-in, but when I wanted to do the late check-out, I couldn't because they said someone else was coming to the apartment.
Bottom line: don't include it; it's better to say that you may not be able to do it unless you arrange it in advance. Inform the customer; that's all.
