Don't hesitate - book it now! 11/10 place to stay.
An amazing studio packed with every amenity you'd need for a short stint in the city. I found it the perfect place to kick off my week in NYC as a solo traveller, and S&G were fantastic hosts and were kind enough to offer a flexible / late check-out to align with my later departure time. The apartment is exactly as described and pictured - a fourth floor walk-up, very compact etc. - but it's been so well thought out that I didn't find any of these elements posed a downside (even lugging my bag up the three flights of stairs - what a good workout!).
Also located in a very convenient spot in the East Village, within 10 mins walk to the Q/R/N, 4/5/6, L (and probably a few others I forgot) but very walkable if you'd prefer to skip the subway and just get around on foot.
