We had a great stay in the Romana apartment. It is virtually brand new, fully kitted out, and was perfect for our family of grandparents, parents and babies. Romana was also able to provide cots x 2, high chairs x 2, and a baby bath ... all very helpful.
The apartment is a short walk to supermarkets and the Metro. The city is only 30 minutes walk if you're feeling more energetic.
We had a fantastic stay and would highly recommend Romana apartments.
