We chose the apartment because of the location and the published photos and have to say that we really loved the place.
The pictures show exactly what you will find (something not always happens): a renewed apartment with new kitchen appliances and can accommodate 6 in it's 3 bedrooms.
It is located very conveniently on Sagrada Familia area, 2 blocks away from the famous church and the metro. It's on a 1st floor with elevator. However, the internet and wifi (which we required) was not available, since the communication company couldn't install it prior to our stay.
Elsa was very kind and accessible for every time we needed to contacted her.
I really recommend this place (I have already did so) if you are going to Barcelona with your family.
