With their detailed restoration of period ceilings, doors and stained glass windows, El Palauet Living Barcelona would certainly be high on my list of beautiful hotels to stay at! The building on Passeig de Gràcia was built in 1906 . The restoration resulted in six Modernista, fully equipped suites.
Personally, I would be staying there just to admire the ceilings! I also like the combination of the contemporary furniture with the classic architecture; they play against one another.
