Sheraton Grand Hotel & Spa, Edinburgh

Excellent hotel & facilities. Modern, spacious interior. Complementary wifi, pool, + gym. Very helpful staff. Spa and breakfast are typically not included, but upgrade is possible for 90 GBP per day for 2 people. This includes access to the club lounge, the spa, unlimited drinks and snacks from 5:30-7:30pm, and breakfast in the lounge in the morning. If you wanted a greater selection for the breakfast, you could pay 5 GBP more per person for the breakfast at the One Square restaurant downstairs which includes a quite large selection of hot options and a large continental breakfast. All in all, the food and drinks were amazing. The spa was great - there is a heated hydropool and then multiple types of rooms around it: hammam, rock sauna, aromatherapy room, biosauna, etc.

The location is a little further from the city center than I initially anticipated, but it wasn't a huge problem. It was about a 15-20 minute walk to the Edinburgh Castle and 20-30 if walking at a brisk pace to George St, Princes St, etc. where all the shops are. There isn't much to do around the hotel itself, particularly at night - it seems like a business neighborhood + convention center next door.
