I had a great stay at Sebastian place. The flat is lovely, well équipes, the room is really like a hotel room, big, with a lot of closet to store your cloths, and a big bathroom.
Kitchen is fully equipped but the oven doesn't work.
You can do the laundry if you bring your own product. The whole place is clean and with a Cody lovely atmosphere.
The district is popular, not very beautiful but alive without being too noisy.
Sebastian is very nice, the only problem is if you don't speak Spanish the communication is a bit difficult.
I recommend this flat completely !
