What a terrific and unique experience. Mari y Petz really care about this place and it shines through in every detail. The apartment is completely eco-renovated and it is extremely cool. I will be bringing some of these ideas home with me. It is also very well situated, we ended up walking everywhere and it never seemed like a long walk. They also left us a wonderful breakfast basket that was educational and delicious, couldn't have been better timing. Next Barcelona trip will defiantly include a stay here.
