My wife, our two kids and I stayed for a week at Juan Carlos and Nina’s apartment. Nina welcomed us at the apartment and showed us around, as well go with us to the parking garage. We found them to be very gracious hosts who also made great sightseeing and restaurant recommendations and also promptly answered our texts when we needed help. They also stocked the fridge with eggs, ham, water juice, bread, coffee as a welcome package. The apartment is in a great location, 15 minute walk to Plaza de Catalunya.
One issue we ran into was with the business located below the apartment having automatic doors. As early as 5:45 in the morning, you could hear the doors opening and closing, making it very difficult to get any sleep during weekdays.
While the bathrooms are nice, one issue we encountered was the bottom of the showers being extremely slippery. My 5-year old son fell the first night. We ended up placing a towel on the bottom of the shower to prevent future incidents.
Overall we enjoyed our stay, found the apartment safe and welcoming.
