We stayed 2 nights at the Adler on a small-group tour and this was one of the better places we landed. The hotel is a very pleasant, modern, white building with black trim. Rooms are done in brown tones with African-themed bedspreads, upholstery, shower curtains, etc., and though that may not sound like the last word in interior design, in fact the rooms were very pleasant (see the photos). There was a fridge in the room, but there was no facility to boil water for a cup of tea or coffee. Our room at the back of the property on the ground floor was very comfortable - nothing to complain about, except perhaps that the reading lights by the bed were inadequate. Breakfast was the standard Namibian affair, meaning a blend of English and German styles. Staff were helpful and friendly.
The hotel has an indoor heated pool, which would be preferable to the cold Atlantic most of the year.
The location by the waterfront is a plus, though, as the previous reviewer noted, there is a huge building between the Adler and the ocean. We walked everywhere from here (within Swakopmund), and had no problems, and didn't mind the opportunity to stretch our legs. Dinner at the Grape Vine, about 15 minutes' walk away, was excellent and is highly recommended: especially if you have an interest in wine. Our other dinner at "The Lighthouse" was not, however, and we cannot recommend it.

A comfortable no frills hotel on Beach Road with secure parking- unfortunately the sea view has been blocked by the new Aquarium and Fisheries Ministry but still a quiet pleasant base for a few days. We swam in the sea, warmer than the English Channel(just) and walked to supper although most people use their cars. Swakopmund is a great break from desert and bush. Great sea food at Oceans Basket. Pleasant family food at de Kelder or slightly more upmarket at The Grapevine. All fine but not haute cuisine. A morning with Christopher Nel at Living Desert Adventures is a must as is a boat trip from Walvis Bay with Pelican tours.
