I think hotel Oleana is a very good hotel, friendly staff, good breakfast, clean room, etc. However, comparing with other hotel, it is slightly worse. It is possible because of my room. The location is also very nice.
I stayed on the 6th floor and the ceiling is not very tall, especially near the door of the toilet. The main problem I had was that my room is next to the elevator. Whenever the elevator moves (not even at your floor), there are 2 loud clicking/knocking sound which is very disturbing during sleep. Luckily I brought earplug and it helps a lot. The nearby places are quite loud as well, which was surprisingly a contrast to another hotel next to it.
The breakfast is very good as well. Although it wasn't the best when compared to the other hotel next to it.
Overall I think Hotel Oleana is a very good hotel, despite having some minor thing.
