The apartment is located up on the hill near Begona Cathedral. There are bus stops near and you can easily reach the nearest metro station in 10-15 minutes on foot. German is a great host. He was in contact all the time. He provided us with a lot of tourist info and also with Barik card, which can be used to pay for all public transport including Bizkaibus (e.g. if you want to go to Bakio and San Juan de Gastelugatxe with this card the bus will cost you 1,8 instead of 2,55). Though the apartment is small, there is enough space for two persons and there is everything you may need for several days stay. Highly recommend.
