Isabel is a super host indeed! Always available to help and replying the messages very quickly. The check-in was also very easy. This is a very small and cozy studio, good for a single traveller or a couple. It has everything you need to cook and have a perfect stay. The wifi is good. :) The neighbours are also very friendly. Nearby the building you have many, MANY things: 2 metro stations, ATM, supermarket, minimarkets, drugstores, malls and many options for restaurants and bars. You can also get to some of the city center's attractions by walking just few blocks.
But as you're in the city center, the area can be very noisy some hours of the day, specially on weekdays. Other than that, I had a great and pleasant stay. I'd be back for sure!
