We had a great stay at Koni's house: the place is pretty, very neat and clean, big enough for 4 people. The building is beautiful, rather high-standing. The location is great (very central) , although not in a very "cosy" street (big avenue). The host are amazing - I forgot some stuff in the place after the check out, and Koni managed to meet with me before I catch my place to give me my stuff back! I'll definitely stay there again for my future trip in Barcelona.
