I wouldn't book this property or any of Alejandro's properties because of his rudeness and lack of urgency to fix critical issues.
A few things really ruined our stay at Alejandro's place: (1) First, he said he would book us a taxi from the airport to his place. When we arrived at the Barcelona airport, I called the contact person he gave us. They were completely unaware about giving us a ride and were extremely rude to us about it. Alejandro did apologize, which was nice of him, however when we finally got the apartment ourselves, we had to wait 20 minutes with our huge bags outside the apartment for Alejandro to show up and let us in. Bad check in experience (2) The shower had no hot water. It took Alejandro 48 hours to get someone to come fix it. We spent two days showering in freezing cold water. What made matters worse was that he claimed we were taking too long showers, which was draining all the hot water. We literally took 2 six minute showers and all the hot water was drained. (3) We ran out of toilet paper and Alejandro's response was "toilet paper is provided as a courtesy for the first few days". He only provided a few tiny rolls for 4 adults for 5 days. It's shocking that this basic necessity was a "courtesy" (4) The roof started leaking over one of our beds when it started raining one of the days. Alejandro did not send anyone to fix this even though we brought this issue up to him. (5) We found a cockroach in the apartment. This I can say is slightly uncontrollable and isn't truly the host's fault, but given Alejandro's rude attitude, it made the whole experience worse (we have a picture to prove this and all the other issues outlined above)
He did refund us but only for 1 night (even though the issues mentioned above permeated throughout our 5 day stay). That was nice of him but still did not make up for the terrible experience we had.
Overall, find another property in Gracia (great neighborhood to stay in!). Stay away from Alejandro's.
