Location: Perfect location where you can walk out and see Sagrada Familia. The metro is couple blocks away. Lot of eating places and small markets around. Most tourist places were not too far away with the metro.
Host: Very responsive and friendly. Helped wherever possible.
Apartment: Really small. The two bedrooms apart from the main one are really tiny. Bathrooms are very small too. There is only one WC. The dryer does not work so think before washing clothes. The place was really a lot smaller than what it is in pictures.
If location is what you desire, the place is good, but be aware that you will be in a really tiny place.
