First of all, Susana is really nice and helpful.
Regarding the apartment, is perfectly located : a few streets from the castle, you can walk to the center, the tram 28 is next door... perfect !
It s all clean and brand new, fully equipped. Just a bit noisy because of the bar/restaurant near by. But don't worry, even with this we slept tight.
The apartment is made for renting but people leave things : maps, traveling ads, cooking stuff (oil, salt, etc)... which is really appreciable.

Highly recommended !!!
