Nella was a great host. Really quick and easy communication. The check in was super easy and flexible. The place feels right as home and is pretty close to the center. It has a very arty vibe, so if you're in this field, you'll definitely love it. One of the greatest features is the shared balcony which has a view over the neighbourhood. Nella was always responsive and communicative if I had questions.
Downsides, I'd say December and January are kind of cold months for extened living, though there is an Air Conditioner that you can use during the day, but I bet summer is supper chill to be there. The Wi-Fi is a bit slow if you're working something more demanding (3D rendering and file sharing, streaming or whatever) but ok for browsing and Netflix. Good thing is you have, nearby the building, Dar Ciriola where the great personnel there make marvelous sandwiches, and you can also work there as they have about 300Mb internet speed which is more than great.
Overall great experience!
