What a beautiful space in a historic part of the city! I cannot say enough about the hosts and their beautiful apartment... From the tour maps and welcome snacks, to the view of the river and singing in the streets (there are many bars nearby!), this was a memorable trip in large part because of El Pisito and its gracious hosts.
The Mercado de la Rivera across the street has ALL types of produce to cook your own Spanish meals in a terrific kitchen, while the abundance of cafes/restaurants down the streets are more than enough to choose from for days on end. You won't have to walk far to find the most interesting things to see in the Casco Viejo neighborhood. Keep in mind this area can be loud with nightlife... but it all seemed part of the intoxicating Basque urban environment!
