We had a great time at Javier's place with my family. The apartment is great, it's clean and it is well equipped. It was perfect for a family of five. The neighborhood is calm and there are several metro stations nearby, so you can reach the city within 20-30 minutes.
Javier was very welcoming and helpful, he told us everything there is to know about the place and gave us some tips about the transportation. He was very flexible with the check-in, and he even gave us a lift from the airport as our flights were at a later hour.
Overall, I would highly recommend staying at Javier's place!
