We had a great stay at Rajesh's place: very good location and a stunning view. Close to public transportation, lots of things to do in the area (Caixa Forum - just opposite to the apartment - showed a great exhibition, Mies van der Rohe / Barcelona pavilion was just a 2 minute walk and only 15 minutes by foot to great tapas restaurants at the Carrer de Blai/Poble Sec).
Communication with Rajesh and Natalia was very easy. (Rajesh is happy to allow for late check out if his place is not rented the following day.
Thanks again Rajesh!)
