Highly recommended, you wont go wrong. Isidre is a fantastic host, very helpful and willing to share his insigths about the city, where to go and what to do. His appartment centrally located, just off the Plaza Espanya and 20 minutes from the airport and 10 minutes from the railway station Barcelona Sants. The Metro is 3 minutes to walk too. We stayed 3 nigths, the appartment is in a lovely neighbourhood of locals, with unpretentious amenities like shops bakeries, coffee shops and restaurants. the appartment is spacious, well furnished and equipped. i wish all places were like this, city hopping would be sooo easy.
