I stayed for 4 days in Santo Domingo, Dominican republic in January 2018.
The weather was nice during the winter season. Grinder is popular here and I got dozens of messages every day. I also found a boy house, with an average of 5 to 9 boys at the house. The name of the house is Juanbinbin (use google map to find the location, which is in zona colonial). It has an Instagram account "juanbinbin11" with some boys photos posted. The price is 2000 pesos or $50 US dollars, room included. All the available boys would gather for the client to pick one up.
Zona colonial and calle El conde were quiet and I didn't find any particularly interesting. Cine Lido and Bar friends were closed long time ago.
In conclusion, I am not impressed by the city of Santo Domingo.
