The apartment is nice and cozy, it can perfectly host 7 people. The two bathrooms are very useful with many people in the house. Also, the apartment is very clean. It isn't very close to the city centre but taxis are quite cheap so it's not a big deal. Finally, Carmen and her colleague have been great hosts and have proven to be always responsive and ready to help. my friends and I would definetly recommend Carmen's Apartment!
P.S. Just pay attention to the neighbour, he likes to complain a lot
