We stayed for 4 nights in July. We picked Pablos's place based on the location, size and the appealing photos. Communication before and throughout our stay was easy and effective via Airbnb chat. We found the apartment relatively easily using the useful and detailed instructions provided, although I did need to double check the location as the entrance is tucked away at the back of the 1st floor and can be easily missed. The apartment itself is very spacious for its central location featuring a good sized living/dining area, a well equipped kitchen and three bedrooms one of which comes with an en suite bathroom to complement the main bathroom. There were a number of spare fans available that we made use of as it was a very hot day and we needed to lower the temperature quickly. The supermarket downstairs is well stocked and very reasonable with prices. The location is excellent, the nearby market is a must visit as are the bars and restaurants of Casco Viejo, both are on your doorstep. Links to local transport are also both very close making getting to other parts of the city and beyond very straightforward. Only negatives were a few (not many) ants which we spotted in the bathrooms and kitchen cupboards and the noise from the trams and traffic outside. The latter you can expect with such a location but the former not so much. That aside, a top, top place to stay right in the heart of Bilbao.
