Location is the best. It was a trip with a child, but when we got tired, we went back to the hotel and took a break and I was able to go sightseeing again. Staff was very kind, too. From the rooftop we could look over the roof of Casa Mila and it was wonderful.
The only thing I regret was that there was no storage in the bathroom. I think it would be nice to have places and baskets to put used towels and change clothes.
Anyway, thanks to all the staff, it was a wonderful trip. Spain is far from Japan, but I wanted to visit again.
