I didn't have a chance to meet Regina and Juan face to face, as they were away while I visited their property.
Their apartment is well located in my favourite neighborhood in Barcelona, which is why I chose it to begin with.
There were quite a few issues with the apartment that left a bitter taste (no baby cott, no A/C, problematic shower). I practically didn't sleep at all during my first night there (which has obviously affected the following day). I would have expected transparency regarding these issues, which were well known to the host. Had I known about them in advance, I would have probably cancelled my stay there and have looked for alternatives. The choice should be the traveler's before arrival.
I will add that the host did make an effort to solve the issues, but it was a bit too little, too late.
