The appartment is very well located, better than expected as it is nicer than in the photos. Since it is a basement it is not very bright, but cozy anyway. Actually, the quality-cost relationship is good enough and Ali was always very helpful and timely.
However, there are a few things that could be improved: the apartment could have been cleaner, as we observed "traces" of previous guests. The bed is old and not very comfortable if you are staying for a few days.
Summing up, we spent three amazing days in Edinburgh, and Ali and his apartment helped to it.
