Nice little flat in Leith with all basic amenities, and lots of books to peruse. If you are a newer traveler to Edinburgh you might initially feel it's a bit out of the way from City Centre, but it doesn't take long to find a quick way in, the bus stops are nearby, cabs are generally available (a bit trickier to get a taxi during the Fringe festival however!), and of course you can always make the 30-40 minute trek on foot. If you are a solo female traveler I can imagine the area feeling a bit uneasy after dark, so make sure to plan a ride back to the flat ahead if that's you.
Key pickup as mentioned in other reviews isn't ideal, but Anabel gives clear instructions, contact information and is adaptable if your arrival time suddenly changes.
The only other thing worth mentioning is that we found sound travels quite well from the tenants above (we suspect they have a pet with a very excitable tail!), so if you are a light sleeper, it may be a good idea to bring earplugs just in case.
All around, a pleasant stay!
