My stay at Joel's flat was great. I was there for a month (January 2023), and the flat is more than prepared for longs stays. The kitchen is spacious, I had my own fridge and shelves to place my stuff. It also has oven, microwave, stove, etc. for cooking. The washing machine is also available. Upstairs, there is this nice living room. My room was bigger than usual, with plenty of storage, bright and comfy. The place is super clean. Joel was a great host, he was always open to help me whenever I need it. He's very easygoing. He recommended me lots of places and useful tips to a newcomer in Edinburgh. When my sister came to visit, Joel allowed her to stay in my room and he even lent us another mattress! It has been such a great experience, I definitely recommend this flat for long (and short) stays.
PS: Keep in mind that if you travel in winter, Edinburgh is very cold and windy!
