This is a fabulously spacious apartment right in the heart of Edinburgh old town. Fantastic location in terms of getting about without having to pay for taxis or buses.
That said, as the listing states, it is also in a busy area for bars. There was significant noise in the evenings (and into the early hours) and the staff were busy emptying glass bottles into bins early in the mornings, or the bin lorries were coming themselves.
On balance, the flat is well worth staying in for the space it gives you and the central location, but I suggest you bring ear plugs!
