Dianka's place was awesome! Perfect location for us, in a nice area too.
It was a bit noisy on Friday night, but our earplugs solved that. The apartment is 5 or 6 flights up, so be prepared for a hike (especially if you have big suitcases like we did) - but the stairclimb is totally worth it. The apartment is spacious and welcoming with lots of natural light.
Dianka and Leticia were very accommodating when we asked for an early check-in (to store our bags) and a late check-out (again, just to store our bags).
We would recommend Dianka's place to anyone! Hope we can make it back some day :)
