Excellent excellent excellent! The apartment is spotless clean and has it all (coffee, chocolate, drinks, breakfast oatmeal, toiletries, etc). The bed is super comfortable and big. The apartment is beautifully decorated. Check-in was easy and it even has a parking spot (a priceless amenity in Boston)!
We stayed with our 6-month old son and Jonathan even provided us with baby essentials.
We had a minor issue with the drainage and water, but Jonathan was very quick to solve it. He replies fast and even speaks spanish!
I recommend this place and would definitely stay there again.
