This is possibly the most convenient place to stay in Barcelona. It is very conveniently located next to everything! If you don't know the Barcelona neighborhoods very well, and you are here to see the sights, I highly recommend staying at Marcel's. It is extremely easy to reach from the Barcelona airport. And it is within walking distance to all the major sights. It's the perfect central base to start your travels from. The apartment has all the conveniences you could need and was very clean. (When staying at airbnbs vs. hotels, sometimes the linens are where you notice a decline in cleanliness or quality. But not at Marcel's. The linens and towels were incredibly fresh and had that wonderful fresh laundry scent)
