Octavio is a very nice host who was responding to all the questions I had. It was also a nice touch to give us a box of snacks as a christmas gift! He also helped my parents and I book a taxi to the main station on our checkout day which was very helpful. The apartment is about 45 mins via metro to the city and as mentioned it is a quick walk to reach the metro. There is only one supermarket nearby which closes around 9pm which can be quite early so you'd most likely have to do grocery shopping before heading out.
Heating in the apartment is sufficient although it could be better (quite chilly in the apartment sometimes). The neighbour's dog was barking late into the night on some days but luckily we were late sleepers so it was not that bad. Do check with Octavio if he has the electrical cabling in the house fixed or the electrical appliances as well because it blacked out a couple of times while we were going about doing our things in the house (Drying hair, using the microwave, etc.).
