Yobani organises it, but you stay with the parents who are absolutely lovely. You'll need some Spanish to get by - that's true across Cuba in my opinion - but otherwise an excellent location only a short walk from the Plaza Mayor and very comfortable with drinks available in the fridge (charged when you leave, but good prices). It's also only a short walk from the Viazul bus station so whilst I got a bicycle taxi, it wouldn't be a great inconvenience to walk it! Also a fairly obvious but under utilised option, download a map of Cuba in google maps (on your phone) before you go to Cuba, it will be priceless!

Diana and Isidro were lovely hosts. The room is well sized and comfortable with very effective air conditioning. Breakfast was also nice and varied day to day which was refreshing. I spoke basic-level Spanish and would suggest you would need that unless you resort to google translate all the time, but that's true of everywhere I went in Cuba. Would highly recommend as it was also very well situated, but still quiet.
