Our hosts provided us with very detailed and comprehensible directions. The appartment was exactly like described in the offer.
Angel was very friendly and helpful. We didn't meet Oona, but we're sure that she is as friendly and helpful. :)

The neighborhood was fantastic. Two 24/7 supermarkets with a variety of food (one of them is organic and has a wide scope of awesome stuff), cafés, a bar right across the street (very quiet though). The Tortilleria Los Hermanos is also around the corner and offers great Mexican food for very reasonable prices. The subway is within a 2 min walk.
Also the walls in the neighborhood are covered with street art. A walk around the neighborhood is highly recommended!

The walls of the apartment are very thin. So if you're planning on doing some kind of party holiday, you should probably look for another place. If you need a place where you can rest after along day of walking around the city, it's perfect.
It was very clean, we had everything we needed (plates, glasses, knife/fork/spoon, fridge, microwave, TV) and felt very comfortable.

All in all we can recommend the apartment wholeheartedly!
