We loved our time at 55 Blackfriars. If you want access to all of the shops and historical sites on the Royal Mile, this apartment is ideal. It's one block from High Street (Royal Mile) half way between the Castle and Hollyrood Palace. It's also a 10-15 minute walk to the National Museum, Grassmarket and all other Old Town musts. The apartment itself was very spacious, beautiful and very comfortable. The building is old, but all amenities were contemporary, including wifi. Showers were great and the beds were really comfortable. Super large eat-in kitchen, which we did not use. And, just up the street at 15 Blackfriars is a really great breakfast place called The Larder. Highly recommend the 55&15 Blackfriars combo. The only qualifier was the noise from the road construction during the day and the street revelers at night. The construction was temporary as the City preps for the Festival, but if you're going to be in the middle of the action the only way to beat the noisy revelers is to join them. Did I say the beds were comfortable?
