Overall, I enjoyed my time at Carla's place. I loved the balcony, the sounds of the city, the church bell... the location is great - loads of restaurants, shops, and historical sites within walking distance.
Thankfully Carla was there when I arrived so she could point me in the right direction. Most notable is the first thing I noticed was the overpowering smell of cleaning supplies. That faded away to a musty, old building smell. Probably not much that can be done about that, but if you're sensitive to this, it's good info to know.
Pros: Perfect location, comfy bed, water gets really hot and good water pressure.
Cons: Tiny shower - just big enough to turn around in, smells a bit musty, construction next door, you can almost make out the neighbor's conversation.
