The hotel Castellano is located at the city centre and you can go by foot from there to the Salamanca University attractions.
There you have, even, an interesting annex, part of the hotel, like a pub, where you can sit at the tables around the sidewalk and watch the moviment at Portugal Avenue.
A simple and enjoyable place, good point to support your needs when visiting Salamanca.
Thanks a lot, Mr José and Mr Christian.
