I chose Manuel's place because it is in a neighborhood that I am familiar with and that I like spending time in. It's quiet and pretty residential but still only within 10-15min walking from several great food/coffee places. The room/studio was clean and Rosita, who let me in, was very friendly and helpful.
The only thing to note was that, since it's a room in a house with a couple other rooms that may also be occupied, noise does travel a bit. I got woken up by other guests arriving back in the middle of the night. They weren't being too loud but it's that you can hear when other people come and go and I'm a light sleeper (they do provide earplugs).
Overall, I enjoyed my stay and would stay there again.
