The truth is that I do not give it 5 stars because of the political, administrative and internal organization problems that the university has. It is not a cheap university (it has many specialists and it is also in the capital) but it is worth studying there. Madrid is fantastic and the teachers are great experts in their corresponding subjects.
I was a year of my degree for a mobility scholarship, and the only thing that bothered that year were the continuous strikes of all kinds of staff (cleaning, security, copy shop …) that made the stay there sometimes was not very nice. A year later I started the Master and, again, although it cost me a lot to be able to pay for it, in the long run you can feel the quality of it and you are super pleased to have made the effort and achieved it.
In general, I think it is a highly recommended university to study psychology.
