Communication was fast and all good - even though mostly in Spanish. Check-in went smoothly, so did the check-out.
Some of the positive things:
Location. A couple of bus stops are just around the corner. Taxis are always available within minutes - and the metro is about 8 minutes of walking away. You can reach the old city and parts of the centre by walking (10-20mins). The flat is modern and cozy. Reliable and fast wifi.
Why I reduced some stars:
Noise. Very noisy neighbors almost every night. The entrance door causes a loud boom every time it closes (which happens very often, it's a very big block). Cleanliness. Unidentifiable hair on the duvet (a lot of them) - looked like dog hair. Hasn't been washed in a while. Kitchen is not very well equipped.
