We stayed at Ainara's place for two nights over the weekend. The apartment is as advertised, located right in the Old Town. The spacious room is exactly as in photos, with a spotless private bathroom in the hall outside the room. A continental breakfast was thoughtfully provided every morning: packaged cakes, cheese, ham, two slices of bread, cereal, juice and two coffee capsules. We appreciated the availability of tea and milk at any time during our stay. Ainara was in the apartment most of our stay, and we appreciated her quick responses to any questions either in person or via message.
The only problem we had was the noise outside the apartment. Every night, there were large crowds of young people sitting and hanging out on the street just below our window. The noise would continue until 2-4am. I am a heavy sleeper and managed to get some sleep with the help of earplugs. Of course, our stay was over the weekend, AND we chose to be right in the Old Town. Nevertheless, I would stay outside of the Old Town if I ever visit over the weekend.
