My brother and I had a wonderful 1 week stay at Tana's apartment. The bedrooms and livingroom are very spacious with lots of windows and natural light. The bathroom and kitchen are small but quite adequate. You couldn't ask for a better location with many excellent restaurants and grocery stores within a short walk. There is also plenty of public transportation nearby.
My brother and I like to walk so didn't mind the half to 3/4 miles to the Royal Mile and Princes Street. Uber and taxis are also available if you don't want to take the bus or walk.
Just about everything you could need is available in the apartment and the kitchen even is stocked with more than just the basics.
We wouldn't hesitate staying here again and recommending it to our friends.
