I had a good stay at Celestin's place. My flight was arriving at midnight, I let him know and he left me the keys in a lockbox so I had no issues checking in late at night.
The apartment is on the 5th floor, you need to climb 4 levels of stairs and originally I thought this could be an issue as I was carrying fairly heavy luggage, but I managed it without much issue and during my stay I actually enjoyed getting in a bit of much needed exercise clinking the stairs.
The apartment is quite spacious with very high ceilings and a good design. My room was the one with a hammock, however there wasn't a hammock, there were some boxes and personal items in the corner of my specious room, which did not bother me at all. My room and the sheets were clean, and the bed was super comfortable. I got an excellent value for being in one of the best areas, with metro bus stop directly in front of the apartment and as many bars, restaurants, shopping and nightlife as you wish within walking distance in any direction!
I was happy to have brought my earplugs because there was constant traffic in the main street below.
