Monse's little Donastia apartment was perfect for our short two-person stay. Can't imagine a better location: close to buses while in the heart of old town. Tons of restaurants and bars within minutes, and all the sights were right outside our door (while easier to reach by car / taxi than most areas in the pedestrian zone). The apartment itself was clean, well-stocked, beautifully decorated, and quiet.
Monse was also very responsive and helpful. Highly recommend the apartment to anyone.
