Leah's apartment is super convenient in terms of location. It's literally right next to the castle and you can see it outside from the window! We were able to walk all around Edinburgh without any problems.
The apartment was clean, well furnished, and quiet. Plenty of room for 4 people. The bathroom itself was modern, and I loved the shower! The only thing I wished they provided was hand soap, but everything else was excellent.
Leah provided detailed instructions about the apartment and the checking in process, and was able to answer all my questions quickly. Great place to stay in Edinburgh!
