Luis's place is as advertised. The photos are very accurate and the apartment was very clean. We had everything we needed. The extra blankets and the radiators were extremely helpful, as the weather was a bit more cold than expected in late March.
Easy access to metro and buss stations. We took buss no. 760 most of the time, since its stop was close to the apartment. The supermarket nearby (Sharkar) was useful, because it was open till late. You can also find several restaurants in the area; we ate at O Pepe and the food was good.
We also met Luis when we left. He was very friendly and easy to talk to.
All in all, we recommend staying at his place.
