Right in the very front of the sea: NO street between building and beach. Restaurants, bars, shops, banks, a train station (Barcelona-Tarragona), a port ... All within the reach of minutes by foot. You live very close to the center without the disatvantage of having the noise from traffic, restaurants or bars.
As there is no traffic it is also safe for your children.
A place with these ingredients is hard to find. You will have a great time !
