Carlos and Berta (the staff) are great, you feel like you are staying in the house of a good friend. The location is great, just half block of the main historical buildings and less than 2 kms from Nicaragua Lake. La Casona is a colonial former house that was exquisitly renovated for a luxury hostal with few rooms, a lobby, a garden and a breakfast area. The have really nice furniture and decoration details making the place really cozy. They don´t have a parking lot in the hotel property but they have a place for cars 2 blocks away, so that was fine.
The rates are a higher than the rest of Nicaragua, but nothing crazy. Remember Granada is the main turistic attraction there.
The rooms were great, really clean, spacios and the beds are confortable. Definely a four star category room in such a little hotel. La Casona don´t have a restaurant (they only offer breakfast) but right in the same street you can find a pizza place and other restaurants.

The hotel staff, especially Bertha and Carlos, are warm and welcoming. We stayed for four nights in a very clean room with a king bed. The walk-in closet was spacious and our room overlooked a fountain which attracted lots of birds.
Breakfast was warm and nutritious and the staff was helpful in planning activities such a quiet boat /birdwatching tour of Lake Nicaragua/Los Isletas run by NicaraquaDulce.

Four of us were traveling from our home in Costa Rica overland to Somoto, Nicaragua and stopped overnight in Granada to break up the trip. Made a last minute reservation at La Casona de los Estrada via email at 10pm the night before our arrival. Got an immediate response within minutes from Carlos answering questions and providing pricing/availability information. Unbelievable service. When we arrived, everything was as described and actually exceeded expectation. Super friendly and helpful staff, good hi-speed wifi, super clean, well situated in downtown Granada and an delicious, made-to-order breakfast included. Cannot recommend this hotel more highly.

What can I say. My partner and I traveled Central America for a month, staying in various 2-3 star accommodations in Guatemala, Nicaragua and Costa Rica. What I can tell you about La Casona de los Estrada is that the the 5-6 rooms they have are comfortable, quaint, clean and spacious. For the money (I think we paid around US $50/night), you can't do better. Location is 2 blocks from the central square and all the main attractions in Grenada. Best of all, the manager there (Carlos) is quite a character. Funny, kind and caring man who helped us with everything from where to eat to finding accommodations at our next destination. Breakfast at the hotel was fantastic with a gorgeous indoor courtyard and garden with hummingbirds and the like. Highly recommend. Would stay here again for sure.
