Maria Teresa and Jesus are amazing hosts. They accommodated my late night check in and made sure I was comfortable. The room is better than in pictures, very classy and atmospheric. There are no locks on the door but I didn't have any problems. The bed is huge and comfortable, better than in most hotels. Great value for such low price.
The only thing to consider is the street noise, La Latina is a bar area. Especially if you gonna stay over weekend, make sure to bring earplugs, they really help.
