Great place to stay and great, friendly host. Spacious room. Very homely flat. The place can be a bit difficult to find but Sandra's instructions, which she sends out in advance, were very helpful. She's also great for local recommendations. The best thing about the flat is the excellent location in the heart of Edinburgh, you're a very short walk from most of the major attractions in central Edinburgh!
The only bad thing was the noise from the local revellers on Friday and Saturday nights, which was to be expected given the location, so make sure to bring very good ear plugs before you arrive if you are staying over the weekend.
The room door also does not have a lock on it, so bear this in mind if you're planning on bringing valuables with you and leaving them in the flat. I felt very safe staying here and had no issues, but it would have been very easy for another unscrupulous guest to go try their luck with my things if they wanted to.
