My stay at Cathal's was amazing! The check in was super easy and Cathal was very hospitable and nice. He even took me to some major city sites! The room itself is beautiful and the apartment very characteristic - perfect for a cosy Edinburgh stay! The apartment is also very close (5 mins) walk to old town, which is very convenient, so you won't be needing to call a taxi.
Overall such a great experience and would highly recommend - I'll be coming back for sure!
