Small and relatively expensive (12 euros) for what’s offered. Having said that, there are some nice pieces of furniture and stained glass. Also, they show work by Gaudi, Puig and another famous guy who I cannot remember right now. Also, we were introduced to some other reasonably decent creators of art deco. So what’s the bottom line? If you are coming to Barcelona for the first time and you are staying no more than 3 days, forget about this place. There are much better options for your time. Hell, the Picasso Museum is vastly superior. On the other hand, if you are coming back for a second or third time, like us, and you have used up most everything else, then what the heck, go. You get to kill 30-45 minutes of your day and if you enjoy this stuff, you will be satisfied with the time spent, if not the money.
