Maria is very friendly and accommodating. I arrived with a cold/fever and during a record-setting heat wave. Maria made me a soup one day! Being sick impacted my experience because I wasn't able to rest with the heat. I recommend that you confirm with her about your intentions for the use of the air conditioner. Energy is expensive, so it is very common to always turn lights off, air conditioning off, etc. The apartment is on one of the main east-west streets of Gracia (a one-lane road) and only busy during 'rush hour'. Otherwise, it is pretty quiet even with windows wide open. Everything you need is very close.
