Calum was a very helpful host. I left one of my bags on the train on arrival, and the rail company contacted Calum, when they read my Airbnb booking in my bag. He and his friend went to great efforts to contact me with the message that the bag was found. He also tried hard to get the TV fixed when the aerial went wonky, but that wasn't a big deal to us anyway. The flat was cosy and bright, even better than described, well equipped (including a hairdryer) and very well located in funky Portobello. The stairwell of the apartment block is a bit dim and daunting at first glance, but is absolutely safe and OK.
