The apartment was comfortable and really close to the city center (the street was indeed one of the most famous ones for "pintxos" bars). Joseba was a great host, very communicative, charming and interested in our personal background. He made our check-in process really easy and showed us from the beginning all the house's rules to share a comfortable space all of us.
However, there was a big problem in our experience in this apartment: his wife was a really unwelcoming person. Whenever we crossed each other in the common areas and we tried to interact with her in different languages (just in case this was the problem), she remained always silent and looking angry, she never had any warm word to us, the opposite: the only moment where she spoke to us (in an angry way) was to remark one house's rule we missed by mistake. This created a really weird atmosphere each time we had to share the common areas (kitchen and entrance). We wouldn't come back to the apartment due to this.
