The apartment is really nice! It is very true to the photos, except that when we stayed a large sheet had been put over the couch (which presumably we were meant to sit on, instead of directly on the couch???) and a plastic cover had been put over the table. Both had the effect of feeling to "cheapen" the apartment and make it less homely. It was a shame as the furniture underneath was very nice.
The terrace is lovely, with a nice deck chair and table setting. The bed was very comfortable and the bathroom was nice too.
We enjoyed the location in Gracia. A fun area to stay in.
As other reviews mention, there are a lot of stairs, so you should consider whether you can get your luggage up there! The person who did our check in kindly carried one of our suitcases up the stairs.
It is unfortunate Joan doesn't provide much in the way of amenities. No toiletries were included. We had to go buy more toilet paper during our stay. There was also only 3 coffee capsules provided (we booked 3 nights, but surely for 2 guests you could provide at least 6 capsules) and only 2 dishwasher tablets. It seemed like unnecessary cost cutting...the apartment is comparable to the price of a nice hotel and it would not cost much more for enough of these things to be included. It's a small gripe though - just be prepared that you may need to make a visit to a supermarket during your stay for these items.
