Angel is a superb host, really flexible and ready to resolve your things asap. The apartment is central (centro historico) and the building has security personell. It's near Alameda Central / Bellas Artes. The streets though are not the nicest around. If you skip those 2-3 streets you can enjoy many magnificent places within walking distance. The apartment itself is clean and decorated nicely. The room has enough space for anything and has a good bed.
