The apartment is really nice, clean and all the furniture is new. The fact that it's a triplex is a real plus because you have a lot of space even with 8 people and there are 2 balconies which is also great when the weather is nice.
The location is perfect because there are bus stops 2min from the apartment and it takes you downtown in 10min. Or you can walk (30min).
Aritz is a great host ! He was really helpful : he gave us good places to go and useful numbers, he even made a reservation for us in a "sidrería". He's nice and available if we need.
I definitely recommend this apartment and I'll come back for sure !
