As a family of 4 we stayed at Federico’s apartment for one week.
Plus side: The apartment looks like the pictures. It has a bit of a hotel feel to it as all draws, wardrobes etc were empty so it was easy to find space for our clothes and things.
There were enough towels and sheets there so we could change the bedding as we were there during a heat wave and it was hot. So, it was nice to be able to do this. It’s an easy location to get around with good links to public transport.
It is a functional and easy living type place with good cooking facilities, comfortable bed, good wi-fi, washing machine and dishwasher.
Down side: It was a little small for a family of 4 (2 kids age 7 and 13) but if you are going to be out most of the days it will work out. It’s on a busy high street with a lot of traffic so bring some earplugs if the weather is hot and you want let some cooler air in while sleeping.
Take pictures of the keys when picking them up and contact Federico if you think something is missing. We had an issue were the garage fob was missing when we arrived but didn’t notice as we didn’t have a car.
In general, I think it’s a cool place for two people and Federico has set it up to be comfortable for two and accommodate 4 if needed.
