We really enjoyed our stay. Period. The short version is that we'd highly recommend this place and stay here again without a doubt. A few details to make this more useful.
When we got to the lobby, there was a particular scent/smell. Not strong, and we could not tell what it was and we probably got used to it. It was not bad, probably being in an old city with old buildings. We booked a regular room first, then decided to go up to a park view one, and were not disappointed. Incredibly nice view above the trees on the 10th floor. The room was bigger than expected, comfortable and clean. And the view was just a nice, green welcoming thing every morning.
Two things to keep in mind: if you want all friendly smiles 14/7, this is not it. Some front desk folks were super nice and friendly, others were still correct, but more on the serious side, not a ton of emotion, smiles or anything. Not bad, just probably unexpected when the person that received us the first day was friendly. English was understood mostly. And you may find there is a VIP thing in hotels.com for this one, but the money won't give you much here as there is no room service, bar or restaurant. They did have some free snacks and water, coffee, etc and they left a banana and some more snacks for us daily. And the neighborhood is quiet and nice and good location, at the center of everything we wanted to do. But depending on your style, maybe far. We loved walking 5-15 miles per day... or you may need to jump on train?
