Ricardo's place is well located and clean, it's a bit smaller than it appears on the photos but very cozy, good beds. We had all we needed and we saved a ton of time by not having to travel every day to the center.
Ricardo was helpful at night when we arrived and the doorman couldn't find the keys.
We only had two issues during our stay: The internet was very very slow and we had trouble to get past the door with that digital PIN pad - personally I was just successful once at getting in, had to wake up guys every time I got in late.
