I stayed in Guillermo's lovely apartment for 2 months. It was incredibly light and airy with high ceilings and a really modern feel. The apt had everything you needed, it was super clean and Guillermo was great at keeping in contact and being around if you needed anything at all.
The bedroom, bathroom and living room are all a great size for one or two people and you also have access to a lovely garden on the bottom floor.
Perfect location only 3 mins from the L train which meant a short 10/15 ride to the city. Some great food and drinks spots close by and 2/3 delis in the area. I would stay there again in a second!
