Catarina's apartment is an absolute gem!! And she's an incredibly nice and interesting and helpful person. Catarina really knows what she's doing, and she's renovated her apartment very tastefully. It felt like a home-away-from home for me, and though I always loved roaming the city and surroundings, I also looked forward to returning to her apartment to recharge, it's so welcoming and comfortable. The Bairro Alto neighborhood is definitely lively, and ideally located. It's not a quiet neighborhood, but if you want to be directly in the middle of Lisbon, in an incredibly vibrant, colorful and historical area, as I did, this place couldn't be more perfect. It's lively mostly at night, during the days it's much quieter and charming and filled with character. It's walking distance from several of the best Lisbon neighborhoods, and is filled with local restaurants, bars, nightlife, and most of all, filled with both local Lisboans and tourists from all over the world. It's a microcosm of Lisbon itself, and when you walk out the door of her charming apartment you're directly in the middle of one of the best neighborhoods in Lisbon. The apartment itself couldn't be any nicer. Catarina has thought of every possible thing - the kitchen is completely equipped to cook nice meals at home, and completely stocked with very tasteful dinnerware and utensils. The bed and bedding are quite nice and comfortable, and the whole space is warm and charming. It's ideal for a single person (as I was), and also perfect for a couple, and even a small child. The bathroom has been renovated very nicely, and even has a fantastic small washing machine that works very well, with two large outdoor hang-dry lines easily accessible out the windows (and lots of clothes pins to use for hanging!). Her WiFi is great, and again, every time I looked for something, I was able to find it, Cat has really thought of every thing a traveler might need. She had paper bags, plastic bags, a great fan, an extremely well-stocked kitchen, plenty of nice-quality towels and extra bedding and supplies. Though the apartment is in the middle of a lively and bustling neighborhood (which is one of its best attractions) when you close the extra-think windows that Catarina renovated with, it's completely quiet at night, and dark too, with the wooden shutters on the windows. It could be bustling and noisy, or completely quiet and dark at night, perfect! Catarina was also completely available and responsive the couple of times I had questions, and, when my initial flight got delayed for a day, and I came in on another flight at 6:50 am, Cat even offered to pick me up at the airport (for 20 Euros, a great deal!), just an unbelievably kind and thoughtful effort, and brought me to the apartment, and came inside as I settled in and admired how lovely it was! Again, I couldn't recommend "Cat's Cool, Cozy in Lisbon Center" any more highly!
