Inigo's Airbnb was such a lovely place! It was just as described and the perfect size for my friend and I to stay in. The flat itself was very bright and airy which might make it difficult to sleep in the morning but during the day it's quite lovely.
The only downside is that it is a little bit outside of the city center but it is located directly next to an U-Bahn station that takes you directly to the Hauptbahnhof. Inigo was such a great and friendly host!
