This was a good place to stay for being out and about, but there is no natural light in the living room or kitchen, so if you plan to work from there, you are basically in an interior office. The small patio area shown in the pictures is really just a place for hanging laundry and has no furniture to sit on (unlike in the pictures). The bedrooms are too small to work from, unless you sit on your bed.
The wifi was good enough for both of us to be on video calls at the same time.
We were given access to the largest bedroom shown in the pictures, but none of the others displayed. I stayed in a room that does not match any of the pictures. We asked for the other rooms to be opened, but the host wouldn't show them to us. We were only two people but not a couple and expected to have access to all the rooms.
The place is located by both major train stations - the inter-city one and the regional rail - as well as the metro and is in good walking or biking distance to everything we wanted to do. To get to Ruzafa, a popular area of restaurants, cafes, nightlife, etc., you walk in an underground tunnel for a few minutes. It's okay during the day when it's busy, but is quite empty at night. Walking the long way above ground only adds 10 minutes or so, but does make everything much further than it appears on the map.
