Our party of five had a wonderful stay at Maribel's flat. Maribel's son Jorge met us at the apartment, explained everything and was our contact during our stay. He is a great guy, and very helpful. The apartment was clean and had all the furnishings, towels, cleaning supplies, toilet paper etc.
Each of the three rooms has windows with blinds and comfortable beds. The internet access was fast and flawless. There was a TV connection but we didn't use it.
The flat has easy access to the O'Donnell metro stop, and is close to an airport express bus. The surrounding area has lots of stores, restaurants, markets, and pretty much anything you need within walking distance.
Maribel and Jorge even helped us with a suitcase storage problem we had.
I'm struggling to find anything negative. About the only problem we had was that the sun wasn't shining on the day we washed our clothes, so they needed to dry over two days.
Highest recommendation!
