Luis's apartment is lovely, and exactly as described. It's in a great location, and we (4 adults and a 15 month old) were very comfortable there. Luis was able to provide us with a crib, high chair, and lots of toys for the baby to play with. The water pressure in the showers is wonderful, and we never had an issue with hot water. The gallery turns into a balcony with the doors open, so we were able to enjoy our evenings out there with a glass of wine. Luis was very responsive both before and during our stay, answering any questions we had.

A couple of potential issues: The interior of the apartment is very quiet, but there is quite a bit of street noise in the two main bedrooms. Luckily, none of us had an issue with sleeping through it. (The third bedroom is located along the interior atrium, so traffic noise wasn't an issue in there.) The elevator is quite small - we had to collapse the stroller to get it in, then only one person and the stroller could ride the elevator, while someone else would have to carry the baby up or down the stairs (or wait for the elevator to come back). Neither of those things bothered us, though, and we would still recommend this apartment to anyone staying in Barcelona!

(One trick we learned towards the end of our stay - even though the Passage de Gracia Metro station is a bit closer, it's a mess to navigate. Try walking an extra block to the Diagonal station - so worth it!)
