My stay was 5 nights so I would say my review can give you some ideas about Mayra's place.
Pros:
1. Location: This place was located in the very heart of Gaslamp district with near access to lots and lots of tourist spots. You can get to convention center/seaport village/USS midway/little Italy etc. by walk.
2. Free Parking: As parking fee was pretty pricey in SD, you save lots of money staying in Mayra's place. The parking structure was located 2 blocks away from the apt and it was covered parking. Very convenient.
3. Quiet: Considering the fact that the unit was located in such a busy district with many restaurants and bars, if you close all windows the unit was quite quiet (read Cons for another prospective)
4. Sufficient kitchen tools and you get what you need to prepare a nice meal. Also Washer and Dryer were provided.
5. Free food and water in the fridge.
Cons:
1. There were blankets left in the washer an dryer: At the day before I left, I tended to use washer and dryer and when I opened them up I found some blankets inside both machines... they were cleaned but damp and I have no idea how long they've been staying in there.
2. You'd better wash all kitchen tools before you intend to use them.
3. During my stay the AC was not functioning as it should be and because the bad air from restaurants besides the unit kept coming out so we had to close windows at all time, therefore the unit was not quite cool even at night. And at the last day of my stay Mayra had someone fix this issue so I guess this issue had been solved already.
4. You can always hear people above you walking around since the ceiling was not thick.
