Pros: This is a lovely space which is located in easy walking distance (about half mile or 15-20 mins leisurely walk) to the gothic quarter, Sagrada Familia, and Arc de Triomf where the train station is located. There are several convenience stores located close by. Judit was easy to get in touch with. The house comes with lots of appliances eg. microwave, stove, multiple coffee makers, multiple fans and strong AC (great for the humidity!), and all the utensils needed for a family to stay comfortably. The style is also interesting -- I'm guessing the decorations are inspired by artist Miro.
Cons: If you are very self conscious and need more privacy for #2, the bathrooms are somewhat open, like doors don't lock and you can kind of hear everything. Also the bedrooms are not that private except for the upstairs one.
If you have only 2 couples, a group of friends/family used to sharing everything then it is perfect. I came with a group of 7 people and it was good. Overall I have no other Barcelona homes to compare it to, but I would still highly recommend this place.
