We stayed at this apartment with our family of 8 persons. Place was nicely located to the centre and El Prat airport with busstops near the apartment (5 min walk).
Apartment had everything we needed and was as described. It has two rooms with double beds, one room with single bed where you can pull out an extra bed, one room with bunk beds. The living room has 2 couches where one couch can be transformed into a double bed. Some matrasses are less comfortable but it didn't disturb us.
Living rooms has airco, other rooms have a fan, but it can get quite warm in there. It didn't bother me, but one of the kids had trouble sleeping due to the warmth.
Martha was very very hospitable and welcoming, extremely sweet! She really took time to explain the area and this was highly appreciated by us.
We would definitely come back here and recommend this apartment.
