I've been all over the UK and Ireland and Edinburgh tops my list of favorite cities to visit. The people are very friendly and the city is full of stuff to do whether you are on your own or traveling with family.
This apartment is in a great location allowing you full access to transport, restaurants, and other activities. Edinburgh castle is in easy walking distance. Blair has worked hard on providing an information guide that is very detailed and helpful.
The apartment is easily accessible but there are a couple of flights of stairs to climb before you are there. It's something to keep in mind if you are elderly, disabled or have trouble with stairs. I didn't notice any lifts in the stair area.
Once inside the apartment, you'll notice a kitchen with a large fridge, two modern looking bathrooms with two showers and fairly spacious bedrooms. Be aware that the water pressure is quite low and it may take a while to fill the tub. There is also a living room with a TV and some sparse furniture.
The bedrooms are set out to accommodate a larger group of people but be aware that most of the beds are single fold-away beds and are not very comfortable.
Overall, it's a decent apartment with lots of potential. You will love the proximity to the city.
