Elkarlos,
Guess it's time to do a TR for that trip
My take on Casa Tomas. Decent apartment upstairs, 3 bdr. one bath w/suicide shower. Small TV, portable cd type jam box. No AC, so open the windows during the day. Internet was pretty good I recall.
Maid arrives in the morning around 10:30, she does the basics, leave your clothes out and she will wash, dry and fold them. She will also cleanup any dishes from breakfast or the previous evenings dinner.
The landlord lives downstairs and is a nice guy. Chances are he may know a few of your dates....in a biblical way
Take advantage of the outdoor jacuzzi, girls loved it.
Only complaints would be, beds were the 4 inch foam type. Luckily for me and my friend at the time we weighed in at total of 240 lbs, but if your a bigger guy and like your women the same, bruises may occur
The living room furniture probably needs to be updated, it was well worn at that time. We found out at an unfortunate time that toilet paper was rationed 
Two rolls per week, so if you have a couple of chicas drinking foo foos all week by all means buy some at the store.
All in all, I would do it again, nice break fron the hotel scene, if you like to cook a meal or two there is adequete cookware. Also he has a grill if you want to BBQ, just need to buy some charcoal and starter. The girls enjoyed the peacefulness of the property, and it is a 5 minute walk to SL. If you are a light sleeper, you will awake to the sounds of the animals from the Zoo directly below you, I personally enjoyed it, I rise at 6 am daily. Another thing I recall is he has four (4) doors that you have to unlock to get in. If you think you may be a little drunk when coming home, put the keys in order on your key chain! Colombianas from the DR are so impatient when they know cookies are upstairs
but having OralB as wingman and your personal bitch to cook breakfast and bake cookies might be cool.
