I cannot think of any reason anyone would stay anywhere else in Barcelona than Magda's appartment. It is spacious light airy with a balcony with great views, a huge living room, a nice sized kitchen. There is one fantastic big ensuite double and then at the other end of a long hall - 3 other rooms which sleep 6 more people. It would be great for a family and kids - have them at the other end making a noise. It was perfect for our large group of 8.
It was very quiet as on the 3rd floor. There is a lift.
No negatives at all
