What a great apartment. Very clean and ideal location for easy access to major sites, yet on very quiet street. Airy and bright rooms, Good washing machine and air conditioning. All indication this is a well loved home rather than a motel-like rental.
Indeed there are stairs. The rooms are on multiple levels and this apartment is not appropriate for anyone with mobility issues. I am 72 and my partner 76 and we had no troubles. The upper terrace is sublime.
