I'll repeat what was said already - Sandra is a great host! and I am very satisfied with my stay. She, being very friendly and courteous, took care of me as soon as I arrived and was making sure I feel welcome. We had a nice chat over a cup of tea in the evenings and Sandra was always ready to advise on the next museum / place to visit.
The apartament is very cosy with all the facilities you need after a day in Edinburgh - a hot shower, fully-equipped kitchen, a cup of warm tea or coffee and a couple of friendly and well-mannered cats.
This room will be #1 on my list when I'd be visiting the city again.
