We did not stay with Mahmoud after paying for the reservation, as A) we were unable to access the unit by bicycle and B) did not feel comfortable sharing a space with him after experiencing his rude behavior. More explanation below for your understanding.
1. Location: Located in the heights of the city, difficult to access especially by bicycle, wheelchair, etc. The address given will take you down and up several flights of stairs if you follow googl maps, and the host did not provide directions to access via bicycle (avoiding stairs).
Before we arrived, we asked if the place was accessible by bicycle with paneers. Mahmoud simply said yes. We followed googl maps from >50km away and the directions took us to a stairwell with at least four flights of stairs. This is by no means accessible by bicycle to carry bicycles up stairs. When we noticed even more stairs behind the gate and asked him how many more stairs via text, he responded saying "Not too much", expecting us to carry them up. It was not realistic to carry the bicycles and paneers up the stairs after riding 70km that day.
2. Rudeness: Mahmoud was very rude and condescending, saying "Bro, you went the wrong way", regarding his incorrect answer to our question about the unit being accessible by bicycle. Other users have complained that the place was not very accessible and up very many flights of stairs, yet he did not tell us there was only one specific route to take to avoid stairs. He put blame on us, who have never been to Bilbao before, rather than attempting to correct the situation. When we told him that we were very tired and unable to carry the bicycles up the stairs after riding so far, his only response was that he was also tired because of having to stay up until 11pm to assist us. It was 11pm when we arrived, which he had agreed to prior to accepting the reservation. He did not come down to offer directions or assistance until 30 minutes after we first contacted him to notify him that we were unable to locate the unit via the directions provided by googl.
It is a good idea to thoroughly read other reviews before making a booking here.
