I only have the highest recommendation for Elisabeth's listing. On time, she showed us around the flat, the beautiful terrace, all the facilities and supplements in the flat. When she realised I had my little daughter with me, she immediately called her husband who shortly after showed up with a bag full of toys.
The flat seemed smaller than on the pictures, but had everything I could've asked for and more. If you're aesthetically interested the flat is for you - it's minimalistically decorated, wood and lighting where you need it - it's the perfect home styling for the size that it is. I kept on finding beautiful and smart details that made me enjoy it even more.
The area was everything I'd wished for; small, quiet street, all the beautiful small Gracia streets to wander, coffee shops and a fantastic Italian grocery store around the corner for when I couldn't help myself. Likewise, if I walked in the other direction, Sagrada de Familia was only a short walk way. It's even visible from the terrace, so is the ocean!
I can highly recommend this flat, actually in summer as in winter.
