The apartment is one of many similar apartments located in a hotel, so the one we stayed in was not actually the same as that pictured, albeit similar. It is well located within walking distance of Sagrada Familia and a number of metro stations.
The one we had suited our needs, albeit was not the cleanest apartment we've stayed in and the bathroom did not ventilate well, the only openable window backing straight into the lift shaft. That meant towels etc had quite a musty smell to them.
Overall, if you simply need somewhere to sleep and base yourself this is fine but isn't somewhere you would spend much time relaxing.
