Oscar and Susana’s apartment was a great place to stay for three nights. It was very large and very well equipped. We did use the kitchen for cooking and had everything we needed. We found the washer/dryer to be very convenient being right on the porch! The apartment was private and in a quiet spot.
We came from the Barcelona airport by taking the metro. It was very easy, requiring only two trains, but did take an hour.
I also want to note that there is a security system installed in the apartment. There are two cameras set up, but we were reassured that these cameras were only used when the apartment was vacant.
