Serafin's apartment was spacious, clean and well equipped. It is located in a safe and quiet neighborhood with a designated parking place in the garage, which we were grateful for since parking can be tricky in the city. Casco viejo was about a 10 min walk and the Guggenheim was about 30 min. Walk from the apartment. We felt safe walking around even at night. Overall it was a great place to stay in the city.
