I had an amazing stay in Natalias place! You get exactly what is promised in the description and even more. Location is also great!
The room itself is spacious for one person. The bed is comfortable enough, but it can be little bit too small for a couple. The apartment is in a busy location and you can hear the noises from the street pretty well. So be prepared with some earplugs if you are not that good of a sleeper.
The hosts are very welcoming and they make sure you have a pleasant stay! They really respect your privacy but at the same time are very eager to help you with everything! The place is also a private art gallery so be prepared for that. It is not a walk-in so it wasn't that busy during my stay and therefore didn't bother me at all.
Overall, I can certainly recommend this location for your stay in Edinburgh!
