Driving from airport area: get on Expreso Baldiorioty de Castro/PR 26 and continue as you pass Condado and curve into the road that takes you into the Old San Juan area. At the entrance of Old San Juan, there’s a plaza, and the road on the right (straight ahead not the one going up) is San Francisco Street. Turn left on San Justo, go down one block, that is Fortaleza, turn left. The building will be on your right hand side. It is blue (only blue one on the block!). The lockbox is the 2nd one and the code will be provided the day before check-in.

Traffic varies, but from the airport it should be 20-30 minutes.
