First, Jordina's guesthouse is one of the best accommodations I had in my experience.
The place is a bit from the city centre, but it is only ~15 minutes walk to the main square of Puigserda.
The guesthouse has its own parking space inside the "farmhouse area" with gates; hence you may be 100% sure that your car is safe at night.
The shared space on the first floor contains several tables, a fireplace, a chillout area with books and games, and a yoga room. All furniture is either new and stylish or old (in very good condition) and even more stylish.
Breakfasts deserve a separate article, but in two words: they are unforgettable. Consisting mostly of local 0km products, they can provide an ideal start to the day.
The room was great in size, equipment (all that you need with very high quality), and atmosphere (the house is definitely well built with care). The view from the windows is very nice, as it shows the nearest mountain range.
So, summing up, it is 100% recommended.
