We loved our stay at Ruben's place. He was out of town whilst we were there but we were met by Teresa who was so accommodating and more than happy to help us out with any queries. It is in a great location, walking distance to union square, so many delicious restaurants/cafes and a number of tourist spots. The apartment it's self was very clean and comfortable, great wifi and good interior heating. The building is quiet with little to no street noise. We would definitely stay here again!
