I stayed at Alejandra place for three nights. The location is perfect, all major tourist attractions are walking distance away.
The interaction I had with Alejandra was nice, she and her mom were really helpful and recommended some cool places.
The only downside was that the room was really cold the first night I arrived. They provided a electric heater but it took few hours for the room to warm up. Also, the internet only really worked in my room if I moved my device close to the door.
