When we stayed at Iván and Carmina's they were away on holiday so we didn't work with them at all. I tried communicating with Carmina to arrange our arrival but it was on the difficult side given I didn't have a phone to use in Spain and could only rely on Wi-Fi to text Carmina via the airbnb app. Her friend was supposed to meet us at the apartment to let us in but because we didn't have a phone we stood outside for almost an hour while I attempted to get a response from Carmina with Wi-Fi. We ended up stopping a kind stranger on the street who let us use their phone to call Carmina's friend to let us in. It was a long and very hot day of travel so we were very frustrated with this whole process as we sat on the street.
Once we got Into the apartment it was smooth sailing from there, mind you it is on the 4th floor with very narrow stairways so with large luggage it takes some effort, but aside from that the space is just as pictured and very clean. They have an AC unit which was a godsend given the hot August heat. We had everything we needed in the apartment and found it easy to walk or take the bus to everywhere we wanted to go. There is also access to a bonus space on the rooftop where there is seating, and washer dryer. Overall it was an OK experience. The apartment itself was exactly what we anticipated.
