I'll decide our review in 3 sections
1) Location: could not ask for a better location. All Metro (underground subway) stops within a walking distance. It is beautiful, it is safe, and it has lots of restaurants and markets around. Also the tourist busses (Hop on/Hop off) stops right in front of the apartment. Really could not ask for a better location.
2) the apartment itself. It is much more spacious than the pictures make it seem to be. It was amazing for the two of us and could easily fit a family of four. It is clean and has two massive windows that open up to a great view. It has all the amnesties you'll need. The only thing is that if you have a disability that prevents you from going up the stairs, there are no elevators and there is 3 flights of steps to go up on. It wasn't an issue for us but just so you know. The pictures really don't do it justice. We had no complaints. Towels and everything else is provided. It is very clean, safe, and quiet. (If you are really picky with your pillow then bring your own, other than that you will be more than fine).
3) the host: he is amazing. He met us at the apartment late at night. Was great with suggestions and was very friendly. He showed us around the neighbourhood the next day and made great food suggestions. We would definitely stay here again.
