My girlfriend and I had a very nice stay at Eduardo's place. The room is spacious and has a cute balcony overlooking a garden. The kitchen has plenty of storage space and everything you need for cooking your own meals. Eduardo was super communicative, flexible and helpful (he even left us a map of the area with marked places of interest).
In terms of location, the apartment is in a quiet residential area very near a beautiful lake... but also only a ten minute walk to the main road where you can catch a bus/train to the city center. We definitely recommend staying at Eduardo's :)
