Not stayed at either of the hotels as I mainly go to the South of Tenerife and this could be a reason that there are not many reviews available on here or elsewhere.

There are one or two members who holiday in Puerto de La Cruz and may be able to help with location and general opinion of hotels although not stayed in them

HI if you go to the tenerife web cams at the bottom of the page there is a link to a web cam on the hotel perla when you get in you will be able to see there web site

Web address for hotel perla is http://www.hotelperlatenerife.com

hope this helps with one hotel yours the fatboy
