First of all, I didn't stay at Bernardo's and Eva's place listed on Tobasco street. The morning of our booking, Bernardo called to let me know there was a problem with the electricity. He offered me another apartment above his shop and it was AMAZING!!! Better I think than the one we originally booked as this one had two bedrooms, two bathrooms, living room, kitchen, and patio.
We've stayed at many Airbnbs in Mexico City and this had been our favorite thus far. Bernardo and Eva take such good care of their apartment. It was clean, stylishly done, and felt like a real home with fresh flowers and everything. Not to mention you can't get a better location. And Bernardo is great with communication. He's super friendly and always responds immediately. We even got to meet him as he was outside his shop quite a bit.
I can't say enough good things about this place. It's the perfect place to stay in Roma. :)
