Karina's apartment has a private bedroom, bathroom, living room for guests, so it feel like useing the entire house.
I was really comfortable and happy to stay here for 5days.
Many supermarket, restaurant are near apartment and the Sants and Espanya Station is located nearby, so it is super convenient to go outside. Also, you can see Montjuic Park & museums on foot and take the bus to Moonjuic Castle.
I recommend " Just stay here when you travel in Barcelona ! "
PS: when you get a shower, you have to be careful! If you don't, water will be splattered from the shower booth and wet on bathroom's floor.
