We had a great time in Emma's flat, it was clean, comfortable and really easy to find. The space was perfect and everything we needed was provided (towels, toiletries, kitchen utensils, and snacks).
It took about 5-10 mins to walk to Portobello high street and then 10-15 mins on the 26 bus into the centre of Edinburgh. The park opposite was also really nice. No wifi which made it difficult to plan and research the rest of our trip, but wasn't a huge issue
Would come again! :)
