Great appartement, very spacious, clean. Saya and Diego were excellent hosts, communication was always very fast. We had a late flight and they were very accomodating in letting us store our luggage at their place after checking out.
King-size bed was super comfy. Couch-bed was less so but perfectly acceptable. Shower was amazing: hot, clean, great water pressure. Fridge and microwave were very handy to warm up leftovers from restaurants. Coffee machine was great.
The only downside was some (light) noise at night from footsteps upstairs (which was a problem if you were sleeping in the living room, not in the bedroom) and the radiators (which would keep clanging loudly when the heating was turned on, only a problem in cold weather).
Location was quite out of the centre (average 40 mins by subway to central manhattan) but we knew that going in. Neighborhood itself was very multicultural, nice and lively day and night with plenty of places to shop / get food.
