Daniel's place is perfect - the room is just as described, small but really comfortable, with a nice big window for fresh air overlooking a quiet back street. And the place is spotless.
The neighbourhood is great, I loved it. It's busy enough that you have eveything you need at your doorstep (including Metro station, 3 stops from the old town), but at the smae time has a great small 'hood feel to it. I really enjoyed walking around and discovering the alleyways, staircases and murals - be sure to make time to explore this area.
Daniel was easy to communicate with and he is very pleasant to chat to and interact with.
I highly recommend it.
