Believe everything you've read about how close this apartment is to the castle. I wish I could post a picture. Yes, there are stairs but that's part of Edinburgh's multi-leveled charm! The apartment building isn't new, but it's warm and easy to navigate. If you can, I recommend bringing smaller light bags to get up stairs and around the hallways.
The bed is spacious and very comfortable and we enjoyed the selection of movies (finally watched Shaun of the Dead!). We didn't take advantage of the kitchen beyond refilling our water bottles at the sink. The shower was a tight fit, but that's not surprising in Europe--just surprising to Americans.
The only reason for our low review is the internet issue. We arrived and checked in fine but spent nearly 30 minutes trying to get the wifi working with very little instruction. Finally, I turned my data on my phone and saw a message from Terry about an issue with his provider and there would be no wifi during our stay. This was quite disappointing in 2020 and we just needed to mention it.
