The air conditioner is only in 1 room and one in the passage. this was fine as it was visible in the photos but our biggest issue with the apartment was that the air conditioning wasn't functional. It was extremely hot in Barcelona and we we had to keep getting in touch with the host to get the air conditioning repaired (which was tried by him however it was all in vain). Arne did definitely try to get it repaired but it would work for an hour or so during the day and then stop again.
Also, the second bathroom was very small and photos weren't clear about the size of the same. We were 2 couples and with all of us being tall, weren't able to use it at all and eventually we had to share the same bathroom.
The living room is just like a small room with a table and tiny bench. The sofa is just in the corridor near the entrance so as such a bit cramped.
Overall the apartment was located a 10 minute walk from Sagrada Familia and also to Gracia which has plenty of bars and restaurants.
The check in process was smooth and we received an early check in, however an official checkin time of 5pm is quite unusual as compared to 2 or 3 pm in other bnbs.
