The stay at Betty and Anthea's place was lovely. I liken it to visiting my Italian aunt and cousin, if they lived right next to New York City. Betty and Anthea were very friendly and accommodating. Their basement home is incredibly close to the M and R lines, and from them you get incredible access to the whole of Manhattan. It was very comfortable while I was there (spring); for those visiting in the summer, Betty noted that the air conditioning originates from the living room, so there's a standing fan in the room to help cool or you can open your door to allow the air conditioning in. The room has a closet to store your items in, and a TV with air channels if you are so inclined - but I spent most of my time talking with Betty and Anthea in the living room. I would recommend that if you want more of a solitary experience, looking elsewhere to stay would be best. But if you're looking for an experience of Astoria family life as part of your NYC journey, you can't get any closer than this.
The road they live on feels residential with a strong sense of community, and felt secure during the evening. The area in general is probably as secure as a close suburb of NYC would be. Your room is secured with a key, though I never felt the need to lock my room even when my possessions were in there and I was out. The bathroom is narrow but very functional; the water is hot and with good pressure. The bedroom is quiet. The bed is a standard size twin bed, of a cot construction with a 4" foam mattress. I found it completely comfortable to sleep on, which surprised me - probably due to the good foam mattress. I mentioned to Betty the idea of a bunkie board to remove the sag, and after I left she messaged and said she added it. So I think it'll be a fine bed if you're not really tall. Checkin was very easy, and Betty and Anthea are awake later in the evening to check you in and give you a set of keys for other nights. Be sure to message Betty when you arrive, because finding the entrance is tricky.
