Carlos's place is conveniently located right off the highway, but you can't hear any of noise from inside the room. Getting to downtown San Diego was about a $10 uber ride, 10-15 minutes.
The room itself was perfect for a quiet place to come home to- not terribly big, but just big enough to not feel cramped. Place was very clean, shower was great. Although Carlos was kind enough to provide K-cups and tea, unfortunately the Keurig wasn't working. This was a very minor inconvenience but doesn't deter from the place being a great value overall.
