Pros:
Comfortable for 5 people, friendly, good space and a lot of natural light in the kitchen and living room.

There are several restaurants, cafe, and shops within walking distance
The red bus hop on and off tour is waking distance to a stop
We highly recommend the Bueno Aires Grill Restaurant (steak place with a cool behind the scenes surprise bar)
Things to consider:
Breakfast buffet is expensive but good
Everything in the room has a fee ..coffee, water, etc., so be careful the cost will rack up quickly.
The beds are not advertised correctly. There is actually 2 full beds and a room with two twins pushed together to make a queen. We anticipated a full, a queen and two twins as advertised.
Bring your own hand towels if you need them.
If you purchase their taxi service it is convenient but just do it one way. You can get a taxi much cheaper on the way back to the airport. Their company will also charge you more if your party needs different terminals. They wanted to charge us 20 euros to drop one group at terminal 1 and another at terminal 2.
Overall, lovely stay in Barcelona!!
