This is a fantastic place to stay, but you should know that it's not for everyone.
The main pros are the space itself and the people that run it. This place is literally a mansion, albeit an incompletely renovated one. It's always a wonder to walk through its (difficult to open) front doors. My bed was comfortable and the bathroom available to me was well appointed (though I had a nicer one than the listing describes due to ongoing renovations). Lina and Alex were attentive, friendly, and more helpful than they needed to be hosts - I couldn't have asked for better. I also took individual Spanish lessons with Maria, who is a charming and hugely overqualified instructor who lives in the house. Thanks to them, I thoroughly enjoyed the 12 nights that I spent in this home.
The cons: I visited in the summer, and it was HOT. The room comes with a fan and a balcony to combat this, and you can always escape downstairs or into the cozy garden, but you should know that to stay here in hot weather you'll need to be tough. You should also know that it's an old, incompletely renovated house, and things inevitably go wrong. After a rainstorm the hallway was slick with rain that had leaked through the closed windows. At one point the water flow shutdown, delaying my shower for hours. Days were spent without wifi. None of this was the staff's fault - they worked on these issues immediately as they arose, and were very responsive and apologetic with requested updates. Just know that this kind of thing happens.
I would definitely stay here again, though. It has a homey, communitarian feel, and the price compares very favorably to the alternatives with equally good locations in town. All in all it was a great start to my trip!
