I stayed with Andres and his lovely cat Zeus for 4 nights. The location of the flat is very good - easy to reach from the airport and it's also really uncomplicated to get to the city center (10-15min by bus which leaves ~50m from the house, 20min when you're walking). If you want to go to the beach, you can choose between the touristy beach (Malagueta, near Paseo del Parque, 20min by bus, 35 when walking) and a lesser known beach (San Andres?), which is 15min by foot from the flat.
The room itself looks just like in the picture, it's clean and spacious, offering two beds, a desk and a huge wardrobe. The matress is really comfortable and I was given towels, too. As a bonus, the room has a fan which allows you to sleep better in the heat. The bathroom and kitchen were fitted with everything you need and I had the chance to store groceries in the fridge. The house itself is clean and has an elevator, but since the flat is on the 2nd floor, I didn't use it.
Andres himself was very friendly and charming, responded quickly to my texts and was very quick to organise my check in when my flight was delayed and he couldn't be there. All in all, I can really recommend his flat and Zeus' cuddles! :-)
