The house where you'd be staying is incredibly beautiful, extremely clean, well decorated and with everything you will need.
About the room: the sleeping area is tiny but the bed is great. The bathroom is amazing, you will love the shower.
The location of the place is perfect, a hidden area with a great view of the church. The 28 tram stops just around the corner and it takes you directly to the main tourist places or connects you with any part of the city.
Just some things to take into account: getting there with heavy luggage might not be easy, make sure to talk to Victor for a special car if that's your case (most uber and taxi drivers don't go all the way up to the house).
Also, the room is on the ground floor next to the common spaces so it can get a little noisy if there are many other guests in the house (there were 6 of us when I was there). In addition, the patio of the room had the motors of a couple of air conditioners.
In short, the house is incredible, safe and special, but these things are to take into account when booking.
