Fabulous, clean, stylish apartment in perfect location, heart of San Sebastian. Please note, check in at this property requires you to download and use an app (an app that we've never once experienced in our hundreds of Airbnb stays). Before check in you must download your photo ID and also a photo of your face plus your signature. It is ONLY via this app that you can unlock the 2 doors to enter the apartment, in the beginning AND throughout your stay, everytime you leave and re enter the apartment. We almost had to cancel our stay last minute due to the app not working on one of our phones before we checked in and Gregorio informed us there is no other way to enter the apartment. Thankfully we had a second phone to use and the app worked on this phone. But be warned - if you leave this apartment during your stay and your phone goes flat whilst you are out, you will not be able to get back into the apartment without the app. Otherwise the apartment is fantastic.
