We stayed a couple of days at Lilian's place and truly loved it!! We felt very welcome by Lilian's family and they have really been accommodating (we arrived a little late). For instance, Lilian bought a bottle of milk for our daughter's breakfast while there was a couple of beers and some sangria left in the fridge. You can't feel more welcome than that!!!
The place is stunning! Very clean, bright and brand new as we saw on the pictures. Tons of closets, very nice bathroom with deep bathtub and top-notch kitchen. All beds (including sofa-bed) are really comfy and we appreciated that after walking all day long in NYC! We had all the essential and more to feel at home. The roof deck is really nice as well and sure is a unique add-on during the warm season.
The location is great. The apartment is less than five minutes walk to the Subway station, Starbucks and CVS (on 125th St). There is a not-so-expensive (for NYC) parking lot on the 124th. You'll need ~10-15 minutes to go down to Times Square and ~15-20 minutes to the World Trade Center by the subway. People we crossed in the neighborhood were friendly and there are nice and good restaurants close by (Lilian provides a list).
Overall, we had a great experience and the only negative point that I can think of is the fact that we did not stay long enough! But we'll be back!
