Here was our room ...
The bed was really comfy. The TV had lots of channels, including local and American shows. Sometimes a channel would get weak and disappear but eventually would come back. WIFI was complimentary and I found it was strong. Every morning until 10am during the week and 11am on the weekend there is a complimentary buffet breakfast with a good variety of hot and cold items. We would have a big breakfast before we headed off for the day and didn't need to eat again until suppertime.
The hotel is off the beaten path a bit but is just a 10 minute walk to Haymarket area where you can catch trains across the city or elsewhere (we caught a train to Glasgow and back one day and also to Queensferry), trams and buses. There are buses that pass by the hotel on a regular basis. Transit seems really efficient. It's about a 20 minute walk to the Royal Mile, Edinburgh Castle, etc.
There is no restaurant in the hotel but strangely (but it was handy) you can order drinks (wine, beer, mixed drinks, etc.) from the end of the reception desk. You can either drink them in the lobby or take them to your room. There is small menu of foods you can order from them too. We ordered a chicken and bacon pizza one night (it's all they had left for pizza) and it was really good ... the crust was stuffed with tomato sauce, which was fun.
It would have been nice to have a mini fridge in the room as I like having cold water handy. I also like having a morning smoothie but didn't take any ingredients because of the lack of fridge and the powdered greens I mix in with my smoothie need to be refrigerated.
The towel situation was a bit odd ... there was one hand towel and two HUGE bath towels and that was it. I'm sure if we asked we could have gotten more hand towels and perhaps face cloths but we managed without.
We hadn't thought about outlets being different than in Canada but were able to buy a couple adapters at the front desk. If you are just plugging in your phone, etc. there are ports near the power outlets (we had laptops so needed to use the outlets).
