I stayed in alvaro apartment for 2 weeks with family. It was a nice place and cosy. Alvaro is very helpful and the 4:00pm book out time was great for us.
In addition to being fully furnished there was a complimentary drinks in the fridge, napkins and huge supply of towels.
The area is pretty safe we never had an issue, houses in the vicinity are upscale I strongly advise to have a walk and enjoy the architecture in the neighbourhood.

if you want to crash in a comfy quite place not too far from downtown I personally recommend this one.
