"I highly recommend working with Louise Torrisi at Mirador! She was extremely responsive, professional, and committed to finding my perfect apartment. Louise dedicated both her personal and professional time to finding my unit and helping every step of the way. It made a normally stressful moving process, both easy and enjoyable. I recommend working with Louise for all real estate needs."

"I had such a wonderful experience searching for apartments with Simon Goldthorpe. He listened to what I was looking for / what was important to me and found a number of options to present to me. He was always punctual, reliable, polite and professional. I found so many other real estate agents to be pushy and salesy but Simon was the most respectful. I highly recommend working with him and I will be reaching out again in the future!"

"We were moving to New York City and overwhelmed. We looked at 100s of places in person and online as well as spoke to lots of real estate agents claiming they would help us. We spoke with Besnik Hakaj who works with Mirador and all expectations were exceeded! He helped us out in the City looking at multiple different properties while informing us about each one individually. Once our trip ended, he continued to excel and even helped us secure a place that we are super excited about! He went above and beyond, and made the process easy to understand on our end. He got us everything we wanted and more! Besnik and Mirador are the best and if you’re new to looking in NYC I would highly recommend working with them."

"Boyfriend and I are moving from TX to NY, and we started the process of finding/looking at apartments by ourselves. We were overwhelmed and not seeing anything that we liked. We interacted with other brokers at many viewings, but Besnik stood out with his warmth and honesty that we wanted to work with him to find our new home. After listening to our concerns and must haves in a home, Besnik presented us with great options within our budget in a timely manner. He is quick with communication, and goes the extra mile. We signed a lease and are excited for our move! He even checked in a couple times after signing to make sure things are going well and that we’re happy. Great working with Mirador, and ask for Besnik! He is a great guy that cares!"

"I first reached out to Louise Torrisi at the end of January 2022 for an April 1 move-in date. I was told by many agents before that it was too early to start renting for this time period and nothing else. Louise informed me of the same but gave me her personal cell and email and told me to contact her towards the end of February and she would help me, and help me she did. I have never experienced the personal service that Louise provided in any industry, let alone real estate. It is difficult renting in New York (I have a history of renting in Ann Arbor, MI and most recently San Diego, CA which was super straightforward) and Louise guided me through the whole process. I told her my desired location and price and she was able to provide me options immediately. The application process was tricky and I needed to use a guarantor which made it more complex but I was in constant communication with Louise via text or phone to make sure all my ducks were in a row when it came time to submit. She braved the cold to FaceTime me from outside the apartment so I could get a feel of the building and the neighborhood (I am still in California and was not able to visit). My application was accepted and she was very excited for me, as our work together had been a huge success! I am moving into a great place on April 1 because of Louise’s personal dedication to serving her clients. I will 100% reach out to her when I need to look at properties again and anyone reading this should too. Thank you Louise!"
