We had a good time staying at My Edinburgh Life. Most of my questions were answered on the webpage, but I had to search a bit to find them out. One item was luggage storage (not large, and it looks like some guests use it to store extra items that they do not have room for. In addition, there is no refrigerators in the room in building 13, so just be aware. Make sure that you take a look at what is offered, and ask questions before you book.
The property is in the Haymarket area, about 1 mile walk from the Royal Mile. What I liked about it, was that I could enjoy the Royal Mile area during the day, and at night get to a quieter section where I could enjoy a nice dinner or a wee dram at one of the local pubs.
What I was a little disappointed about was that there was no interaction with the staff when I got ther, just by email, but they are responsive. The reason for this is that they like to let people enjoy their stay. While they did have some information on Edinburgh, it would be nice to possibly have the following information in each guest room - shopping (to get forgotten items), restaurants, pubs.
