My girlfriend and I recently spent 10 days in New York and stayed at Maribels.
This was my first time in America, and my friends second or third.
The unit is lovely - spacious, clean, secure, all the amenities you need with welcoming little touches like a bottle of wine, fruit, bagels, milk and chocolates. The bed is super comfy. Kitchen space plenty. Bathroom clean and modern. The unit really was like a home away from home and much nicer than being cramped in a hotel. The unit is located really close to the subway and getting downtown took about 20-30mins. Walking to Central Park takes about 15-20 mins from the unit.
Any issues we had were sorted promptly by Maribel and she made herself available to us at all hours. Unfortunately the air con broke down for a few days as a result of a storm (and in the middle of a heat wave!) but Maribel did everything she could to get it working and make us comfortable in the meantime.
The neighbourhood directly around the street was great, with many restaurants, cafes and food markets, however we didn’t like to stay out far past 8/9pm of a night as we didn’t know the area well and didn’t feel comfortable (just at night, day time was totally fine). If we did stay out, we used cabs and Uber’s to get home and not the subway or bus.

All in all we both loved the unit and our experience and send a big thank you to Maribel (and her electrician!) for looking after us. Highly recommend!
