Gorgeous, spacious and very well equipped apartment. Be aware that you have 3 large flights of stairs and no lift to get to the accommodation so make sure your suitcases aren't over heavy!! The beds are all really comfortable and the single room is ideal for a child to stay in, Peter and Ana also made sure we had a travel cot set up complete with linen and bedding for our 20 month old.
Communication with the couple was great, they were very flexible with out check-in and then left us to our own devices for the weekend before a quick check with us on the last day to make sure we were aware of last minute things to do around COVID etc.
The location is only a 15-20 min walk from old town, there is a decent Sainsbury's local at the end of the street for all your food and drink needs. Lastly the bath is massive meaning even I could have bath (6" 1' and basically just legs) but the shower was really lacklustre, I had to run around under it to get wet.
All in all it's a cracking spot for a stay in Edinburgh and great value, the flat has everything you need except a lift but if you're going to Edinburgh I guess you'll be doing plenty of walking anyway!
