We stayed in Lucia's apartment for 10 days. The check in and check out was amazing: we just needed some instructions to get in and leave by ourselves.
As we were there for work and tourism, internet was important and it worked pretty well.
Even if the windows were not so big, the place was super luminous and we could feel the sun entering everyday.
The apartment is not super close from downtown, but there are lots of buses and we could by tickets on the coffee shop nearby. There is also a CONAD (huge supermarket) 5 minutes away from the apartment.
I would surely recommend the place. Attention if you bring to many bags as there are some stairs to get into the apartment.
