I stayed in John’s place for 20 days and the place was great during my trip, there was groceries and restaurants near from the house (and what helped me a lot save money is cooking), the streets are calm and the neighborhood seems pretty safe, the subway is near from the house something about 3 block’s walking and in the station has the express train who gets in downtown nearly of 20 minutes.
John is super attentive and usually no take longer than 15 minutes to answer any doubt. I recommend!
