The best thing about locaweb is that they offer many different plans for all types, sizes or even budgets! They have great customer service to assist with any questions you may need answering regarding your account setup/billing etc so far I am very happy using them as my web host provider!! There really isn't much i dislike but there are some things in their interface which could be improved upon (ease-of use).
If this sounds like something suitable then give it go; everything else will fall into place after once getting used too :) We currently utilise location specific websites where we cater directly towards our users who live within certain locations - e..g Londoners only get access via london sites & info can also easily filter by region allowing us easy management across multiple regions without having each site set up separately.
