We are a family of three (2 adults + a toddler) that stayed at the apartment for 10 days in the end of October for a combination of a business trip and pleasure.
The communication with Luis was perfect: fast, fun, reliable and trustful. Also, the check in and check out went smoothly with personal intro into the apartment despite our late night arrival and a kind offer to stay as long as we need on a day we were leaving (this was much appreciated as it was raining).
The apartment is on a perfect location close enough to the center and yet far from overcrowded tourist-only areas. Having two metro stations close was a big and important asset (as I needed to travel a lot to different parts of town due to two different conferences). Groceries shops, restaurants, galleries, a big park... everything is close.
Appartment was perfectly equipped for a longer stay (we had a toddler, so we cooked, washed clothes etc.) - both kitchen and bathroom had everything we needed and more.
A comfy bed and funky decorations were an additional plus.
I would come back and I definitely recommend this pick! :)
