First of all, Lina is a great host with very fast communication and very flexible with our needs.
The house is very nicely decorated. The lightening in the house is very nice and well thought about and makes it very cozy, especially at night. Internet works fast and is reliable. Amazing kitchen with lots of utensils. There is also floor heating, which was great during the winter.
One con is that it's very dark inside the house, way darker than it seemed on the pictures. The large windows are also blinded (so people from the street can't look inside), so there almost no daylight coming in the house. This makes it unfortunately basically impossible to tell what time it is during the day when you're inside. Since we spent a lot of time inside, this was definitely a bit of downer for us. But if you're away a lot it should be ok, since the lightening makes it very cozy at night.
The street it's placed at looks a bit shady, to be honest. But, the location itself is great! Right off Gran Via. Lots of restaurants and a supermarket around the corner.
