Diagonal comprise the largest of Barcelona’s shopping districts. Located centrally, these three main avenues provide an endless number of mainstream clothing, shoe, and accessory stores. Av. Diagonal, in particular, houses many of the luxury designer name boutiques, such as Calvin Klein, Versace, and Armani.

As is the case when moving to any new city, housing costs are going to make up a large part of an expat’s budget in Barcelona.
Aside from the size of the property, living in the main areas of the city could mean a significant difference in housing cost from the suburbs. A single-room home would be around 250 to 400 Euros per month, an additional room making about a hundred-and-fifty-euro difference, while a studio-type apartment could be somewhere between 400 and 650 Euros a month.  The grand villas usually start at 3,000 Euros per month going up to as much as 20,000.  It is also important to keep in mind that most apartments and houses in Barcelona do not have central heating or air conditioning.
Barcelona has a Mediterranean climate with mild, humid winters and warm, dry summers
