Our overall experience was great, we could only recommend Lourdes' place! Josep, who welcomed us and gave us the key, was extremely kind, because our flight was late and he stayed until midnight to welcome us! The communication with him was great. The apartment itself is definitely big enough for four people, it has all the amenities you need and we even received a bottle of water and wine for a welcoming gift! The apartment is on a ground floor, so it is a bit darker inside, but it is furnished well and it feels very cosy. It is in a very nice district, which can be a bit loud at night, but only until midnight, afterwards it is fairly calm on the street.
In general, we would definitely recommend the apartment. Thanks, Josep and Lourdes!
