Yes….I rented an apartment in Barceloneta a few months ago and I had the local Council and Police knocking on my door. There is a lot of pressure from the locals in many parts of Barcelona who are either being priced out of neighbourhoods or suffering from noise all through the night.
I was thinking more of buying to live in….but appreciate that buying costs are relatively high and there is CGT on any gains.
My reasoning in saying that Barcelona was a screaming buy was that a few years ago aprtment prices seemed to me to be on a par with London. However, since then prices in Barcelona have nearly halved…whilst prices in London have nearly doubled (give or take a little). Hence the relative value.
