We had a fantastic two-night stay in Susie's Garden Annexe. It has a completely separate entrance and thoughtful screening from Susie's garden and so it really is your own personal space. Parking was easy and plentiful when we arrived. Inside, there is a comfortable bed with a Simba mattress and a nice electric shower with instant hot water and decent pressure. Susie has also provided a lovely little electric fire with simulated flames, flanked by two comfortable lounging chairs. There is a fridge, freezer, microwave and small breakfast bar. This is a smaller space, but it is bigger than most hotel rooms. There is plenty of space to relax during the day and it has a very cosy feel with classy decoration and a nice outdoor seating area.
Susie has also paid a lot of attention to the little touches, providing a small bottle of milk, some cereal, jam etc. so that you're sorted for the morning if you arrive late. She is also a lovely host; happy to leave you to yourself but very welcoming if you do feel the desire to give a little knock on her front door to say hello :-)
If you're looking for accommodation in this area I'd strongly encourage you to book in for a stay here; we'll certainly be back the next time we're in need of a place to stay in Edinburgh.
