I absolutely loved my stay here in the Observatory Apartment! I am a solo woman traveler so safety and comfort are top priorities… happy to say that the area is well lit and properly cared for to lend a secure environment. It took a day or so to get used to having tourists right outside my window, but everyone was pleasant and not paying attention to the house interior… the views are an amazing distraction! The kitchen is well-equipped and even had packets of olive oil, coffee beans, cookery etc. I felt so lucky to be able to appreciate the views from Calton Hill till sundown (10:30pm or later). The monuments on the hill are exquisite as well so plan on spending a lot of time up top! Well done to the Collective and I highly recommend this stay!
