If you are wanting a central location in Edinburgh on a road without traffic then the pedestrianised Castle St (so named as it looks directly towards Edinburgh Castle) must be one of the best places to stay just off Princes Street.
The accommodation was spotless with clean bedlinen and warm and cosy when we arrived. We stayed in suite 2 which was at the back and so no noise from Castle Street which was good, however, the fire door closer on the 1st floor hall door allows this door to close with an exceptionally loud bang so there were times when we could hear other Guests coming and going early in the morning and late at night via this banging door. A small tweak to slow the closing down and getting rid of the loud banging noise (whilst still adhering to fire regs) would sort this out.
We didn't watch much TV but did find the using the remote quite a challenge when we tried to tune into the BBC news.
