Mario sent us a link with step-by-step photos for self check-in that was extremely helpful! The apartment is definitely older, so we felt like we were in a museum! It was clean and well stocked though. The apartment building was undergoing construction, so the building entrance and stairwell was dirty and dusty. You have to walk up several flights of stairs... luckily everyone in my family is in good physical shape. The apartment is very spacious and air conditioning and WiFi worked great!
