As a solo female traveler, I stayed at Ana's place for a week and felt very comfortable. It was exactly what I needed! When I arrived, Ana had fresh flowers, fruit and pastries in the kitchen- what a treat! Ana responded instantly to any of my questions and even checked in throughout the stay. You can't beat the location - walking distance to everything!
The only thing I would note is that this apartment is on the ground floor (if that is something that would worry you). The street is down an ally and off the main road. There is a big of noise at night and in the morning, but as other reviews mentioned you can use the fan to block it out. I'm from NYC and this didn't bother me :) I'd come back here in a heartbeat it was perfect.
