Is Year Round Rental Popular Blanes in Los Pinos- ?

Just wanting to get some insight into what kind of people - locals, students, workers, foreigners etc would come to live year round in Blanes?

I don't know the town that well. I live in Barcelona.

I am at the final stages of buying a flat in Los Pinos. Nice building, overlooks a park, close to beach.

Corner flat- so two long balconies, lots of natural light. 3 bedrooms. About 70m2

Real estate agency says most people wanting long term rental looks for 2 bedroom flats.

It needs renovation. 
Will put in new floorboards, bathroom, open kitchen, new electrics etc.

I guess wondering what kind of demand there is. What is average rent/ max rent someone would pay for a nicely renovated flat.
Have been researching a bit- seems average is about 550-650€.
Would need to charge on the high end or a bit more to cover my costs really.

Not too late for me to pull out of deal and mortgage etc :-)

Any clues?
Anyone here looking to rent a flat full time from May onwards? That's when the flat should be ready :-)
Am uploading some photos here- not of the Blanes flat, though of a small 40m2 flat I bought and renovated in the Borne and Barcelona.

We are really proud of the final look- this isnt' the final style we will do for Blanes. Though to give you an idea of what I enjoy doing.
P.S I'm not a commercial company, just an individual with an interest in all of this.
