Stayed for 2 nights location is central to everything and easy walking distance to many restaurants and bars
Room was well setup lots of space and bed was comfortable. Sofa was a bit on the less desirable side but we didnt stay in the room very much.
The breakfast was great it had a good options of items you would expect along with 4 egg options that you could order.
Also if you love dog this is the hotel to stay in it was dog central. I would like to appologize to the few people who missed the elevator due to us wanted to pet their dogs.
Also i want to give a big shout out to the staff. From the check-in to the cleaning and restaurant staff they were super friendly and helpful they truly elevated the experience and for that well definitely be back.
