We stayed at Catriona's place for two nights and had a really nice time. The place was very clean and welcoming, exactly as described in the photos.
We self checked-in and we had no problem at all with that, Catriona gave us all the info in advance so we knew exactly what to do. The location of the house is also really convenient, just 20 minutes away from the city centre with the bus.
Definitely recommend this place and we'll be back next time we are in Bristol :)
