I highly recommend Jose's place. He is incredibly courteous and kind, and really makes you feel at home. The bedroom seemed almost more like a hotel, Jose had set up a few items on the nightstand that really gave the aire of VIP treatment (considering how inexpensive the room is!).
The apartment is not far from the metro station, but if you have bags it will feel like a longer walk than it really is. The stairway to his apartment is narrow, so if you have bulky bags it might be a little challenging.
I will also advise that if you are a larger person, the shower might be a bit tight. I am 5'8, 200lbs and I only *just* fit in the shower. The shower did have hot and cold water; it was a little tricky at first to get the temperature right, but you get the hang of it.
The area around the apartment really was quiet, and I saw many dog walkers and runners around at all times of day.
Jose provided extremely detailed instructions and pictures on how to find his building and access the key box. He also provided a local map, showing where you might find different points of interest (metro, restaurants, etc). He really did an outstanding job of making sure you weren't left hanging.
This room is definitely worth the 20 minute metro ride to the city center, it doesn't even feel that long. It's also a nice rest for your feet after walking around all day, if you can find a route with fewer transfers (I recommend the metro app for that).
