The accommodation is off the city center - the situation as it is in many middle-class "suburbs" of the big cities in the US.
I'm an Early-Bird and I don't like to drive a car privatly.
The bus runs every 30 minutes between 5am/6am (Sundays 7am) and 10 pm towards the overland.
Mexiko is a 40-50 minute ride away - Downtown San Diego about 30 minutes.
A shopping Center is really, really close.
Haven't really missed anything - apart from a small office desk in my room.
An additional door and the room would be en-suite.
Would really consider to go there again.
