Konrad’s place is really nice. It is has been recently updated and well maintained. It was also surprisingly spacious. The location is fantastic - short walk to various restaurants and stores. Longer walk to Old Town Pasadena.
Konrad is very responsive and thoughtful, even to the point of dropping off sweetener for my morning coffee when I inquired whether there was any available.
The one thing to be aware of is that the window coverings are sheer. So if you need a very dark room to sleep well, this may not be the place for you.
Other than that, I would highly recommend this Airbnb.
