Since the airport hotel at San Juan stopped being a Best Western, the Embassy Suites (part of the Hilton Group), is the closest to the airport and so useful for mileage runs. When you do a search be careful that you book the one at 8000 Tartak Street, Isla Verde, Carolina, 00979, Puerto Rico as there is another on the island that is a long way away from the airport. (I made this mistake once, and only once!).
The cab ride is about $15 from the airport, including the airport fee and tip.
Check-in can be pretty busy, but usually moves at a reasonable speed. If you do online check-in the Reception desk usually have your Gold/Diamond HHonors goodie bag waiting for you at check-in:
The bedroom is at the back, away from the atrium which helps with noise.
The beds were comfortable. The view from the bedroom was of the airport but as the closest runway to the hotel was closed for repairs I did not experience any aircraft noise
The hot breakfast is in the same location.
This particular hotel has a small snack station that freshly makes Pizza at a price less than Room Service. I used this on my second stay.
In the morning there were plenty of taxis waiting outside for the 10 minute journey back to the airport.
The hotel sufficed for what I wanted – somewhere near the airport to lay my head. I couldn’t imagine staying here for any length of time I am afraid as I would just be bored.
