I had a great stay at Lucia’s place! I stayed for a few weeks and she accommodated me very nicely - even gave me a larger room when she noticed how long I was staying.
The only downside is it’s not a very social place. I definitely wouldn’t consider it a normal “hostel”. It’s great if you already know people, but not ideal for solo travelers looking to make friends. I was looking for a little social break and already had some friends in Sevilla so it worked for me.
