Great apartment in a beautiful part of Barcelona. Each in block in that part of the city (l'Eixample) is a small gem: shops, bakeries, restaurants, each different in taste and style. Of course you should explore the better-known sights in Barcelona, but trust me, you could spend a week just discovering what each block has to offer!
Tip in the area: restaurant 9. Right across the road and great value for money, incredible food and very nice people, we had our greatest diner there.
Enjoy!
