We stayed in Pat's place for a few days with our kids and our dogs. The apartment is perfectly located (centre centre) to explore Barcelona and is absolutely perfect for a couple with kids. Spotlessly clean and check in was a dream. The fact that it is possible to park your car in the underground parking is a big plus as well as the patio, which was greatly appreciated by our dogs :)!
We highly recommend Pat's place if you are looking for a place to stay when visiting Barcelona.
