A beautiful location overlooking Grassmarket with views of the castle and situated in a great area with endless pubs, restaurants, shops, etc. As many have mentioned the steps leading you up to the 3rd floor are spiral and not ideal for large luggage or elderly individuals, but they were no problem for us.
The kitchen had everything you would need, however, there were no pods for the dishwasher and there were no coffee pods for the Nespresso maker. The place also was not as clean as we would have expected with dust and a dirty/dusty floor.
The windows are not double glazed and due to the location you can hear everything in the streets. We stayed mid-week and I would caution those that are staying on the weekend or during peak season as I imagine the streets would be even louder. While Rebecca has no control over this, the individual in the flat above was very loud and was doing laundry at 2 am each morning and it caused the entire flat to shake - we did not have great sleep!
