I stayed in this appartment for 3 weeks. The flat is well equipped and cleaned regularly (living room, kitchen and the bathrooms) which I believe is crucial in a shared flat and makes the stay very enjoyable
The room I rented is a great value for your money. The bed is comfortable and the room includes a small desk which I used to work remotely and from which you have a good wifi connection. The only two drawbacks I would point out: the room is quite small and the bed, desk and closet take up most of the space + the street below can be quite noisy and since it is not very well insulated I recommend sleeping with earplugs.
Rodrigo is a very attentive and responsive host and he does his best to make the experience as confortable as possible, which is also a real plus! :)
Another advantage of this flat is that you get to meet other people that are often in a similar situation (student, young professionals) and so it is a great place to socialise!
