We used this guesthouse on 3 occasions when self-touring Iceland for 30 days between mid-June through mid-July, 2021 and were absolutely delighted by our choice to stay here. This hotel is literally across the street from the BSI bus depot where the Flybus from Keflavik drops you off! It is also the stop for the Hop On Hof Off bus, and the central location for the entire bus system within the city and the island country. There is also a gas station with food supplies and 2 quick take-out restaurants (Subway and Serrano) between this bus station and the hotel.
We contacted our host, who met us at the hotel, and helped us to check in early. Great service!
We typically book our stays through hotels.com and have NEVER had a bad experience. We also book the cheapest place we can find which is centrally located. Hence, the Travel Inn Guesthouse was a screaming deal. To get to the central area and the front of the Hallgrímskirkja is a simple walk up the hill behind the hotel. If you go out the front door and turn right then continue straight past the roundabout, you will get to the city pond and the governmental buildings including the National Museum of Iceland and the Settlement Exhibition in about a kilometer or so.
We stayed in Room #9 right across from a bathroom/shower on the 2nd floor. Kitchen was small and I did not see a central living room. However, since we only basically sleep there, it was not a problem for us. Our room had it's own sink and was standard size.
