We stayed 2 nights at Colin's flat and really enjoyed it! The flat is perfectly located just off the main road and very close to Haymarket. It's the perfect neighbourhood for eating out (there are lots of restaurants and pubs) and it is just a 10min walk to Princes Street. The flat was very clean and really nicely furnished. We really felt like being at home in this cosy flat.
Colin was a great host and communication was very easy with him. He even checked on us if we had settled in and provided a lot of useful advices where to go for food and drinks. We definitely recommend staying at his appartment.
