Karen's place is amazing. Everything about it was enjoyable for us! When you check in she gives you all the information you need in person and also tells you about some great local places to eat!
The apartment is set up very nicely with a comfortable sitting area, great little kitchen, and a very nice bathroom. The shower is equipped with jets and a sauna which is something I've never seen from and Airbnb before!
It is situated in a very quiet, safe neighborhood which is only about a 25 minute walk from the royal mile. Or you can get a Uber for about £5 to take you to the royal mile or the grass market. Leith walk is just around the corner with a multitude of good restaurants and pubs.
We probably won't be in Edinburgh again for a very long time, but if we were I'd only want to stay at Karen's again.
