Location: The location is perfect; one block from La Rambla at the bottom of La Rambla. There is a Metro station one block away and it's easy to navigate the Metro system. There is a bike rental across the ally way, we rented bikes for the week with helmets. It's called A Bike Rental. They were awesome to work with. There are bike paths all over the city. We rode to the beach, which is very close by, maybe a 20 min walk. The waterfront is a 5 min walk. We felt safe in this location.
Apartment: The apartment is really big and clean. It has a big fridge and freezer, large washer and dryer, great AC for the hot days. Comfy beds, clean linens, towels, good wifi. We sat out on the balcony with our coffee in the morning. Note: if the dryer is turning off with a red warning light, just empty the water from the top left compartment. It's a bit different from what we have in the States. Hot water was great, no issues. Really good water pressure. If it's cold or the washer or dryer is not working, check the electric box and see if the bottom left switch needs to be adjusted. That happened a couple of times, not a big deal, just good to know it's an easy fix.
Communication: The apartment managers were amazing to work with. They communicated right away during our rental process. I will definitely rent from them again if we visit Barcelona in the future. It was easy to access the apartment with the codes, all info was sent as explained in the rental process. It's really organized.
