If you're considering staying here... DO IT!!!
My wife and I went to Spain and France on our honeymoon, and we ended up having one night where we had not made sleeping arrangements. We booked Lourdes place and are so glad we did!!! The communication was INCREDIBLE and Hector (who welcomed us) was SO kind. The room is so quirky and fun, and it came with complementary champagne. Hector greeted us when we got there and showed us around a little, and he was amazing to talk to. This room is located so close to a bunch of sights, and the surrounding area is fun to explore. Even though we were only there for one day, we got to see a whole new part of Barcelona.
My wife and i were in Europe for two weeks and stayed 5 places, and this one was our favorite by far. 100/10 recommend!!!
(One thing to note! The building is extremely old and therefore has narrow hallways. Be prepared to be in some tight spaces!)
