Stayed here in November, 2011. I arrived there really early since my flight got in at 6:45AM. I ate breakfast at the hotel since nothing was open at the time. I only booked the hotel for one evening and technically, I would only get free breakfast the next day. But the hotel staff was nice enough to let me eat free!
The room was clean and roomy. I had a nice view of the river. The sink is rather small. Even though the hotel has free wi-fi, only a small portion of the hotel can get the signal. The room I stayed in doesn't have wi-fi access, so I had to sit in the hotel lobby or in the restaurant to access the Internet.

We travelled around Iceland and unfortunately Hotel Selfoss was the worst hotel we stayed in. I have stayed in hotels were rooms are tired, but I don't mind if they are clean. We had to move rooms as our first room had a weaking shower and cobwebs around the windows.

In the second the rooms still was not clean enough. Rooms on the 4th floor seemed not to have been cleaned for a long time.

The hotel itself is fine, but room did not live up to 2 star standard let alone 4 stars.

To give the hotel their due they did discount our stay but I feel that was due to a lot of complaints.

We stayed at Hotel Selfoss because we couldn't find a room in Reykjavik! We ended up renting a car and discovered that staying outside Reykjavik is great for accessing the countryside: Eyjafjallajokull, the golden circle, etc. Hotel Selfoss is a well deserved 4-star hotel - no, it doesn't have internet in the rooms but in all the common areas - a great restaurant, an ample complimentary breakfast, spacious double rooms, etc. A great value!

Stayed here for 2 nights as part of a tour. Noticed there were other tour groups there, too, because it is probably the only hotel that can accommodate groups. Selfoss itself doesn't have much to offer, except for a nice river. Rooms at this hotel can have river views, which ours did, along with a view of the local church. Best part is that it is one block from various food options. Great hot-dog stand (Iceland being famous for its hot dogs), plus Thai and pizza. By Icelandic standards, this is a vast assortment. Can walk into town; not much there, but while driving through there is an excellent bakery and also a great gelato shop. Found homemade tuna salad in the bakery frig for about $4 U.S. Grab a roll, and you are in business. Good alternative to the ubiquitous hot dog if you are on a budget. Dinner at the hotel was excellent. Breakfast OK with hard scrambled eggs and some meat. Comfortable rooms. Good base of operations.
