We stayed for four nights at the flat during the New Year's festivities in Edinburgh. The place is incredibly well located so we didn't have to take any public transportation while we were there, everything (ceremonies, restaurants, bars, stores, museums, castles...) was at walking distance.
The flat is very cozy and well taken care of, we felt at home.
Anna and Simon were very helpful before and during our stay there, always ready to give us prompt answers and help, in case we needed. They were flexible in terms of check in time, which helped a lot in our schedule.
