A really great location in interesting China Town. Very close to everything we wanted and there were always lots of convenience stores and restaurants open nearby, even late night. We could always catch an Uber very close to the apartment and it was easy to just enter "Barrio Chino" to get back home. If you follow Mario's check-in instructions (especially the photos), you should find the entrance to the apartment no problem (I was nervous about this before booking because of other people's reviews and it really was a nonissue). Regardless, Mario was quick to answer any questions when messaged.
We asked him for a fan the first night because the room was feeling hot and he got one up to us very quickly. It helped a lot, but otherwise it does get kind of stuffy in there. We opened the windows and the french doors at night and I ended up getting bit by mosquitos (didn't think to ask Mario for anything to remedy this because I thought- what could be done?). The doorman is wonderful and it's nice to know that there are good cameras outside the building. We would have loved for the hot water to have lasted longer as it really only allowed for one of us to shower comfortably, so if this is of any concern to you, I'd maybe ask Mario if the water heater can be turned up or something. My husband thought he spotted the water heater in the apartment and it was just a smaller one, so again, why ask if perhaps nothing can be done?
I am still leaving 5 stars because really the only two things I would complain about are seemingly beyond his control. Otherwise, Mario has a very cool apartment in an excellent area and I would really 100% recommend it.
