First off, a clarification. The apartment is #4 Derecha. The listing and the information you get when you reserve do not indicate which floor. Fortunately a nice resident of the building told me it was probably the 4th floor.

The apartment is much bigger than I thought it was. I used the space for a business trip, and used the extra space for meeting with colleagues. It served that purpose fine. The wifi does not really reach into the back of the apartment (the kitchen or third bedroom).

It's a lovely apartment and wonderfully located.
