The apartment is great and exactly as described - location is perfect.
Clau was an especially great host - extremely attentive and communicative.
We had an issue where we locked the front door key fob in the flat (entirely our fault) and she sent someone over to place a backup in the lockbox within the hour. This turned what could have been a very stressful situation (my phone was also dying) into an easy matter. I tried to send some money for cab fare and a tip for her staff who delivered this key fob during rush hour, but she declined to take it.
This was just above and beyond service of a host and greatly appreciated.
I'm very thankful we had the good fortune to stay at Clau's place. Great experience.
