Staying at Ana and Ruben was perfect! The apartment is in 'La Latina' which is a very cosy neighborhood very close to the city center (5 minutes walking). Nice bars and restaurants are just around the corner (tip: visit 'Pajaritos Mojados'!). Ana and Ruben were nice and very easy to communicate with. The apartment is not to big, but ok for 2 persons. It can become a bit warm though. I'll definitely recommend this place!
