Nadir's place is amazing!
Location: Nadir's place location was perfect for our needs, we needed to commute to Manhattan daily and the subway was 5 min walking. There is a grocery store 3 min away, but we usally went to C town, we liked this one better. Restaurants are all over the Astoria, so don't worry about food.
Check-in / response time: Nadir was always attentive and was checking constantly if everything was ok for us. The keys for the place were left on the main door inside a lock with a password, which is very convenient.
Room / Amenities: The room was amazing. The bed is pretty comfortable and the room had plenty of space to put you luggage. The kitchen had everything you ned to make your meals or store food.
I highly recommend this place.
