Absolutely loved my stay at Catherine and Craig's. Checking in was a breeze and had no difficulty with the key safe box (I've struggled with some before). The apartment interior is well-lit, stylish yet very homey. Very clean and with basic amenities. There are signs up in the bedroom and kitchen so you can get your bearings very quickly. The location of the apartment is unbeatable because you're not only right in the heart of Edinburgh, you're flanked by a good selection of restaurants and an eclectic mix of shops on Thistle Street. If you're a light sleeper, the noise from the street/pub/restaurants below might be something to take into consideration. That said, my fav cafes (Urban Angel and Wellington) on Hanover Street which are well worth a visit are less than a 5min walk away. Communication with hosts pre-trip and during my stay was fab. Hosts are very attentive and when I struggled with one of the bedroom windows, Craig was very kind to pop by that day (a Sunday at that!) to sort it out. Finally, I appreciated the little touches around the apartment that make one feel welcome and at home - the selection of cereals (healthy ones like bran for adults and some which kids would much prefer), longlife milk in the pantry cupboard, butter and Catherine's homemade jam in the fridge, as well as a selection of drinks (cola, wine, beer, whisky) on offer via an honesty box. Beats staying at a hotel. Will choose to stay at theirs again if possible when I'm next in Edinburgh.
