The Center itself is very friendly and so are the staff. I did a Cambridge Exam there and really enjoyed it. Only problem is that Google Maps does not have (at least at the time of my review), the exact location of this center, and therefore is quite hard to find. To every visitor, be aware that there is no indication on the entrance of the building indicating where the center is, so you should know it is in the building nº 895 on the 4th floor. I repeat, do not try to find the Center using Google Maps as the sole acessory, keep in mind it is in building 895 at Rua de Santa Catarina.
