We had the pleasure of staying at Charlottes unit in Calton Hill in mid September for three nights. It is a bright and airy unit and is so close to everything.....Prince's Street, Calton Hill, the Royal Mile, the Castle and Holyrood Palace. Note that there are two flights of steps to acces the unit from the street level. We were a group of five seniors and had an excellent stay! Would highly recommend this unit for your stay in the awesome city of Edinburgh!
