The first thing I'd like to say about this place is that the host was great! Maria was very accommodating, understanding, and communicative the whole time.
The area was very walkable with lots of restaurants and cafes. It's about a 10minute walk to Plaza Serrano, where there are a bunch more restaurants and cafes.
The wifi worked well the whole time. As an example, we were able to binge watch a decent amount of a Netflix series without interruption.
