Talk about Super Host!!
Simcha is literally the best. He was very pleasant, very responsive, had excellent hospitality and plenty of great suggestions about DC. They also have a beautiful place. The pictures do not do justice to the space. The beds were comfy, everything was very clean. Their place is accesible to the monuments and center city, easy parking every time we came home. We also walked in to a kitchen equipped with food for us to use if needed/wanted. He even helped me out with food for my small puppy.
Next time we are in DC, he is definitely the first person I'll reach out too. If you are still considering whether to do it or not, do it! You will not be disappointed!
