At first the communication was a bit bumpy, but it definitely got better, almost perfect.
The team at Casa da Suite is very kind. The check-in was easy even on a sunday and the appartment easily to find due to great explanation. When entering the flat a few things weren't working (wifi, shower, light), but everything got repaired quickly. So this was a great plus. The flat was clean, nicely furnished... everything as expected. It's in a nice area with restaurants and a metro station close by.
I can definitely recommend staying with Casa da Suite.
