We spent one week in Ramses apartment with my couple. We really enjoyed our stay, we couldn't choose a better place, the ratio price/quality is excellent. The ubication is really good, you have Union square at 5 minutes walk, and there is plenty of good breakfast/dinner options near it.
Ramses was always in contact with us, he gave us useful recommendations of New York and was open to questions that we had during our stay.
There was also no problem with the keys even we arrived late at night.
In overall, the stay was worth it 100%, so I will recommend it with no doubt.
