Deafcon there are many Airbnb that allow guests and have excellent WIFI do your own research on the app you can find 1 you like and never have to worry about moving hotel to hotel.
I personally myself have used these internet connections with a VPN and had no interruptions while working 8 hour shift remotely in the Rorhmoser area this helps me extends my trips for a few days and save PTO while I enjoy all the young Puta's
ask the host if you can have guests, ask in regards that you have some expat friends you know who live in Costa Rica an will visit keep is brief and simple., Make the reservation for 2 guests , most hosts you never meet in person anyways.
I have been staying Airbnb last 2 trips and so far enjoy it more than the Gulch hotels and never had any issue with bringing in girls I ask them to dress casual and meet them downstairs upon arrival ... I also don't look old enough to be their grandfather either
