Check in with Lisa was flexible, with suitable warning for her in advance. The room was clean and ready at the time of arrival. She has prepared the house well with chargers for phones and alarm clocks in the rooms and so on. The room I stayed in was comfortable and the bed was very large. For a cold city, the heating was also suitable, which ensured a comfortable stay.
The location is good, as it is close to Waverley station (which doesn't get much traffic, so it won't keep you up at night). Everything in Edinburgh was accessible by foot from Lisa's house.
For good coffee, visit Brew Lab and Artisan Roast. All the pubs are quite similar, really. Under The Stairs offered balanced, delicious and affordable contemporary cuisine for a decent price, and had a relaxed vibe.
Shortcomings of the stay included the shocking weather (be ready for it, antipodeans) and the shower had poor water pressure.
