Talk about the perfectly supplied apartment ...There were robes for heaven sakes!!! Juan Carlos left a bottle of wine, bottled water, and even some snacks for us when we arrived, and the kitchen and bathroom were nicely stocked. If you wanted to stay a while and cook in, there are supermarkets and the fabulous Boqueria market nearby.
But there is no reason to cook in when you are surrounded by fabulous restaurants and even the Opera House within a few minutes walk.
This apartment is in the middle of the Gothic Quarter and you are here because it is central to the active nightlife, the Ramblas, the restaurants ... so as Rick Steves says, bring earplugs - especially if you arrive on a weekend. This is not a criticism, but a fact of life in an area that parties late and sleeps little. That said, the bedroom is in the back and cuts a lot of the activity but be forewarned. There is little auto traffic on the street, but it is the main thoroughfare for pedestrians. You are in the center of it all.
Juan Carlos is always available and wonderfully helpful. I inquired about how to get a taxi to the airport (given the lack of auto traffic, I was concerned) and he dispatched a taxi driving friend to pick us up.
I highly recommend this property. If you do come, spend some time ahead of your trip reading about the nearby restaurants. There are many and they range from poor to extraordinary and you cannot really tell the difference without some guidance.
