Karel's place was just what we needed for a three night stay. Check in instructions were clear and there were instructions in the house for everything needed. Karel was very responsive to all my questions and allowed me an early check in which was great.
The place had everything we needed and was very clean. There was coffee which was a pleasant surprise. It is a bit dated, but that didn't bother us. Beds were comfortable. There is a Roku TV so you can access any streaming services you have, but no local TV for news.
There are many great restaurants that are within 1/2 mile. Very walkable location and close to Balboa Park golf course.
