The apartment is very conveniently located. Opposite to El Corte Ingles, it made our life very easy. It is just ten minutes walk from the old town (in a quiet and peaceful neighbourhood, there is no need to worry about the crowd), and ten minutes walk from the train/bus station (easy to travel somewhere else).
The apartment is very spacious. The south-facing windows allow much sunshine through. If it gets too hot, there is always the air-conditioner. The kitchen is well equipped. Everything we needed were provided. Specifically, the wifi is high-speed and stable.
The communication with the host was very smooth. Nacho was very friendly. Not only did he efficiently solve the curtain for us, but he responded to my random questions on WhatsApp as well, which I am very grateful for.
If I had to pick on something, I would say two things: 1) although there is a wide variety of pillows, some of them probably need cleaning/replacing; 2) unless I got the instruction wrong, there are only around 40 TV channels, all in Spanish.
