Brilliant place to stay. Perfectly placed to reach pretty much anywhere in Edinburgh. Less than 10 minutes walk from Waverly Train Station, and bus stops/tours that take you all over the city.
Alan was very professional, gave incredibly detailed instructions on how to find the flat once I'd booked, even gave a video walkthrough on how to find it from the Royal Mile, a lovely touch. Brilliant communication too, always a quick response. Flat was ready a couple of hours before check in which was really convenient, and I was able to leave my luggage for a few hours after check out upon request.
Flat itself was cosy and comfy, clean with all the necessities you need for even an extended stay. Nice big fridge/freezer which was great, meant I could do one big shop for the week relax. There are several supermarkets a very short walk away, and a huge choice of places to eat. Hardly any traffic noise considering the location, it really doesn't feel like you are right in the middle of the city.
Overall a really comfortable and peaceful stay, would highly recommend this place and will definitely be back!
