I don't know whether you'd call it a boutique hotel but i stayed here a few years ago and it was really nice.

hi
go on2 this website and you'll definitly get something great.I stayed in the crysatl palace but to be honest there is so much to do and see in the city you'd be better off going for a cheaper option.

Hotel Àxel has boutique (or used to!). It's really near from Gaudi's buildings and the shopping areas are not very far either.

No idea about relative pricing, I suppose boutique hotels are more expensive than average in general.

BTW it's a straight-friendly hotel, so they expect their customers to be openminded and non homophobic.
