Hola Tupperlady and welcome to TA Barcelona,
Apts with 2 bath are not that common. Have a look also at the Top Question - How do I find a rental apartment?
Barcelona is quite compact and the metro/bus/taxi network is very efficient. Basically the airport is out of town on the left side and the nicer beaches of Barcelona are on the right side. If you stay in the Old City around El Born, you can be a 10-15 min walk to the beach as well as within walking distance of the metro and sightseeing attractions.
