The hotel just booked is opposite. It is free on the first Sunday of every month, but tickets are unavoidable. It opens at 10:00 a.m. and visits the Picasso Museum (9:20). After returning, there is a long queue. It will take an hour to enter, so I have to eat first. Then I look at the chimney on the top of the building from the top floor of the opposite Gaudi Hotel, and then I go in to visit it carefully. This is Gaudi's early work, which is more traditional in design.
