This apartment is in a great location right near La Rambla and within an easy walk of most of the sights in Barcelona. Even though it's on a busy pedestrian street, the sound didn't keep us up at night at all. It was nice to have a little kitchen (though with no oven) and to have some space to relax between sightseeing trips. We were very comfortable there and would happily stay there again!
The place is clean and comfortable, though amenities are pretty limited (e.g., one towel per person, one dish towel, no napkins or paper towels or tissues). We did get a few more dish towels very quickly when we asked for them. The beds are small but firm; we avoided the lower bunk because one of the rungs is broken, but it would probably be fine for someone smaller. The washer was great to have after many days of traveling, though it never got the clothes completely dry. Fortunately, there are lots of hangers in the closet for hanging things to finish drying.
Be aware that the shower stall is very narrow with not much room to move around; it's easy to hit the faucet and accidentally turn the water off (or very hot or cold). Hot water is limited but was enough for two of us to shower every day.
Communication from Anna and Manel was great. We found the place and got the keys without too much trouble, even though we didn't have telephone service. Paid parking was available near La Bouqueria for 51 euros/3 days or farther away for less money.
Overall, we were really happy with the apartment and would recommend it to anyone who wants to be right in the heart of Barcelona!
