Me, my husband and our dog had a very nice 2 month stay in Ricard's appartment. The location is pretty perfect. Very close to Parc de la Ciutadella and Parc Nord, which is especially great, if you have a dog.
Beaches, Clubs and Xiringuitos are within walking distance, as well as the old town and Sagrada Familia.
The appartment is absolutely true to the pictures - if anything it feels bigger and it is well equipped, incl. new AC and lots of kitchen appliances. I especially loved the balcony - it even offers a bit of a mountain view in the distance and of course has lots of sun.
Ricard is a great host, very nice, responsive, in touch and helpful. He prepared the appartment specifically for our needs, filled the fridge for our arrival, explained everything about the appartment, came over, when we ran into small issues and was overall going the extra mile and beyond to make our stay as nice as possible. That even included messages with tips on what to do, where to eat and presents for our dog!
Overall a great place to fall in love with a vibrant, beautiful and exciting city :-)
