Well...next time we will choose something else.
Indeed, the apartment has a good location, near the center, quiet area, view to the park and the rooms are big. But, we didn't sleep well. The bed is small and Margaret is very noisy. You will hear every step and dishes and doors slapping at 6 AM.
Also, the bedroom has a smell of old (not in the good way). Heating and cleaning are also an issue.
Edinburgh is great! We really enjoyed our time in town :)
