We would personally recommend staying in Pedro’s apartment.
It is very central located and just a few steps away from a station of the famous tram 28E. Moreover, its size and interior are totally satisfying made.
Only be careful with the garbage: We had a very unpleasant encounter with one of the buildings cleaning ladies as we put the garbage on the place where the instruction says. There’s a separate trash room.
Anyway, we can highly recommend staying at the apartment.
