Very big apartment, we were five and had plenty of space. The place is clean and have two bathrooms which are super practical when we are in a group. It is indeed on the fourth floor but no problem to climb up the stairs! The location is perfect, near all the activities and 10 min from the metro. It is in the nightlife neighbourhood with a lot of bars.
Margarida was super reactive and flexible! It was very easy to communicate with her!
The only thing to know is that there is a bar in the neighbouring building, so there is noise during the night (people talking outside). You can hear it in the rooms next the street (double bed and the three simple beds). We had no issue to sleep though because the ones that were sensitive to noise did just sleep in the quiet part of the apartment.
We recommend this place!
