Our family stayed at the Halcyon for three nights during the Edinburgh Festival and it was a great choice. Considering that as well as two kids, the family also includes a cocker spaniel, our options were a little limited for a city stay but we got lucky with this hotel. The location is excellent, walking distance to the city centre and close to a number of decent cafes and restaurants (including the legendary Valvona and Crolla). Better still, the gardens opposite are ideal for a quick walk with the dog (even when the weather is inclement as, apparently, it sometimes is in Edinburgh!) and Calton Hill is right behind the hotel for a longer walk.
The rooms were comfortable and the breakfasts were generous and delicious. The owners and staff were all very welcoming - sausages each morning ensured our dog will never forget the visit - and nor will we!
One last note about prices - for the location, the room rates are very good indeed and the special rates for children are an excellent bonus. Parking was also easy and convenient. All in all, hard to find anything to complain about here!
