We visited Vaishali's apartment with our 1 year old twin girls this october and had a wonderful time. The apartment is a bit out of the center, but the neighborhood is nice, with small shops, cafés and playgrounds - and a 10 minute walk to the beach. Across the road is a huge mall with ditto hypermarché. The connections with the center (Bus, Metro and Tram) are excellent and stops are right at the doorstep.

The apartment was very clean, spacious and very child friendly. The kitchen is well equipped, and Vaishali left the cabinets stocked with basic amenities (spanish olive oil, tuna, some eggs etc). Cooking in the apartment and spending some time there (which you inevitably do with young kids) feels very much at home.

Vaishali was very welcoming to the twins, helping us on arrival, rearranging the living room to accomodate the kids better, even leaving some diapers in the right size and asking beforehand if she should buy some essentials.

If you're planning to visit Barcelona with young children, this place comes highly recommended. If we go again, we would certainly make our reservations here.
