We had a great time staying at Marcela's place! Her apartment is nicely decorated and very clean. We were there for Comic Con, so it was nice to have a living room area to spread out our costumes and all the swag we bought at the con (opposed to a cramped hotel room).
Since we had to wake up early for Comic Con during our stay, it was super convenient to have access to the kitchen so we could make breakfast early in the morning. There is a grocery store about 5 minutes away by car, so it was easy to shop for food and snacks.
The apartment is in a really convenient area and there were tons of places nearby to eat, in addition to a gas station and a bank for getting cash. The location is super close to downtown so if you need to get to the convention center or the Gaslamp Quarter, it's a very short and simple drive (I generally hate driving, so driving in a new city makes me nervous. It was nice that getting to/from the apartment didn't involve complicated instructions). Also, the parking in the apartment was very simple so we didn't have to worry about street parking. The apartment is super close to the zoo and Balboa Park too.
Marcela was a great host, making room for our toiletries in the bathroom and being super flexible about check-in/check-out times. She was also available by phone/text while we were there, so it was nice knowing she was around in the event that we needed help with something.
Because Comic Con took up all of our time, we couldn't visit all the sights San Diego has to offer, so we are planning another trip there. We would definitely rent from Marcela again!
