Viviana is an excellent host! The apartment is lovely, it has everything you could possibly need for a long or short stay. Location is also excellent, very close to the subte with easy access to the whole city. Viviana responded very quickly to any little queries we might have and was very helpful. She was also accommodating when we asked for a late check out. Would definitely stay there again if I come back to BA and I'd highly recommended it to everyone. Gracias Viviana!
