Very clean and comfortable apartment. Its located within 5 minutes of the train station and is very easy to locate. Viviana's very hospitable husband was waiting for us outside the apartment when we arrived and kindly helped us bring our bags upstairs because the elevator was not working.
Breakfast foods were provided for us and the fridge was stocked with beverages you could purchase (i.e., juice, beer, water, etc).
The shower was great, lots of space and good water pressure. No issues with getting hot water.
There was a constant drip coming from the toilet pipes that was a bit distracting but nothing you can't get past. A light sleeper may be bothered by it at night but we were ok and slept through it after all the day's sightseeing.
The metro is very close by and there are lots of places to eat in the area.
There is a nice TV in the room too, however we couldn't get it connected to the wifi so we weren't able to take advantage of the Netflix. There was a language button on the TV so we were able to change things to English when available. The wifi is a free network available through a hotel so you will need an email account to access it. But it works very strong so no issues there.
This apartment is very much like a hotel room with a built in kitchenette. Good place for a couple to stay in but would not recommend a family.
