We have spent amazing time in Raul's appartment! It is very well located so you can easily discover old city by walking. Train station and metro (direct line to the airport) are also very close: ~20 min and ~5 min respectively. Raul is a great host! He has allowed us to Check in a bit earlier (around 12pm) and gave a lot of tips / advice regarding the city (places to eat, to see, etc). The only minor point is that appartment has limited natural light (small windows and not in all rooms), but its a great value for money. Highly recommend it to everyone!
