Helenas place is just great: perfectly (!) located but silent, in a very charming house with one of those old elevators like in a movie. The guests stay in a separate area of her flat with bedroom (comfortable bed), living room with fridge and cooking plates, and own bathroom. All is nicely furnished and decorated. Wifi is there, too. Pity that I did not meet Helena personally but she had perfectly organized that I got the keys and was in contact with me to check that I was alright. I can just highly recommend the place! The location is just unbeatable- and the Retiro is so close, you should go there and enjoy the evening mood/ sunset at the lake.
