The place is very well located, it's very large for a city appartment, the homedecor is great as well. You can communicate with Ancry very easily and they(Ancry and her husband) prepared everything for our arrival, it felt so welcoming.
I recommand this place to visit Barcelona !
As I advised you, a better heating system would be great in winter, eventhough the rest of the year it is not needed, the appartment gets pretty cold in winter because the windows are not very recent, sponge for the dishes and free coffee would be a plus as well ;)
