Diego's house is located in a nice building with 24h concierge service; I felt very safe in the neighbourhood even at night, and I could easily find cafés and restaurants in the vicinity, although it is a relatively quiet area. It is 10 min walk from the metro, and 15 from a large shopping center. The apartment itself was a nice 2 room+bathroom. The huge balcony and great view of the city and the mountains adds much value to any stay. I also found the bed very comfortable. The apartment faces the main road so in the early morning you may hear traffic but during the night it was quiet and I had no problem in sleeping. Indeed the house may benefit from some small repairs and improvements, and a little more kitchenware, but nothing that would ruin your stay and anyway it was totally fine for the bargain price I was offered.
