This very well located - right between the Royal Mile and Victoria street which leads to the Grassmarket - apartment is perfectly suitable for a touristic stay, but not for someone who is looking for a place that allows i.e. to work at home. Although it is very quiet in the bedroom it can get noisy in the living room since a bagpipe-player gives a perpetual concert at the street corner in front of the house.
Everything was clean and provided as described, but I felt slightly unhealthy staying there longer because it smelled moldy in some corners.
Apart from that I was happy to find such a good situated place and the communication as well as the check-in worked out perfectly. If you are looking for an affordable accommodation from where you want to explore the city, I can indeed recommend it.
