Our stay at Oscar's place was great. The best thing is the location - it is in the centre, we walked everywhere; and also it is in the most vibrant area, the Lavapies, with bars and cafes; and even though it is located there- it is quiet for sleeping.
The place is small, a bit smaller then it seemed to us on the photos, but we didn't mind - it is fully equipped, and good organised space, with a touch of style of this specific neighbourhood. Not much light through the window, but it is not gloomy, it has good vibe and it is cosy. It is on the third floor (no elevator), but stairs are not too steep. Oscar was really a great host - he waited for us in front of the apartment with his friend, and they helped us with the luggage. Also during the stay he was quick to respond by text on any question concerning the apartment, at any time, and gave us useful info about the neighbourhood places to eat, and events during our stay. We had a great time in Madrid, and the location of the apartment was important for this.
