Sonia's place is perfect, the location is great for the station, the shopping street, the cathedral and is just at the end of the Luis bridge, so great for evening walks on the river front. It's on the first floor of a lovely old building on a road that can get a little busy, but the bedroom is at the rear of the building so is very peaceful, we slept very well with a comfortable bed and a choice of pillows. The bedroom has plenty of hanging space and draws and the rest of the apartment is very well stocked should you wish to spend time there to cook etc, you can even wash your laundry :)
Sonia speaks perfect English and communicates well all of the time, not only would we recommend her apartment but we would certainly stay again.
P.s. Both the cafes across the road do lovely breakfast for 2 people at less than 10€
