We stayed for a period of 5 weeks. Therefore our expectations were different compared to short-term touristy stays.
The apartment is true as described, recently renewed with simple (IKEA) but new furniture. The assistants arranging the place were responsive and helped quickly with our initial requests.
The neighborhood is exciting; the local working crowd is mixed with many young people. Countless authentic bars around and plenty of excellent tapas bars/restaurants; while several places were a letdown in the city center, these bars and restaurants were all fantastic.
Few things which were an annoyance, though, which don't make this place truly pleasant for a long-term stay:
Due to the rainy period and humidity in November/December, there were issues with water dripping here and there; I believe these will be addressed by the owner soon. The bed is very small (190x150cm)for anyone taller; although there is AC and heating, the isolation is terrible. Also, there's no sound isolation.
