Very Good
Pros +
- Property was clean and had lots of space
- Size of the apartment, location, cleanliness
- Nice facility in a nice area of town.
Cons -
- Valet parking is expensive
- Noisy party during part of the night just in the room besides ours. I understand that the hotel is not responsible of the behaviour of their clients, however, the hotel should not allow people to make a kind of karaoke party with plenty of (mature) people all inside a room at 2 am
- Noisy people above us kept us up late and got us up early.
