This is the place! I have stayed at other B&Bs and hotels in Alajuela due to its close proximity to the airport but Alegria is now my favorite. The one level house is huge, clean and very relaxing.
I left the USA on an early morning flight, George met me at the airport and I was able to really relax at Alegria and slept well too. Woke up to fresh coffee, fruit, and really good Banana nut bread muffins.
I asked George if he had a vacancy for the next night. Luckily he did. So I explored Alajuela that day and returned to Alegria B&B that evening to relax in the rocking chair on the front porch, take a hot shower with plenty of water pressure (you don't get that at some B&Bs) and slept like a baby.
Located away from downtown noise and traffic but a taxi fare of about $1.50 will get you to the center of town. George had a Taxi there in about two minutes of his call. Taxi stand nearby.
Too bad there were no vacancies for my last night in Costa Rica but for my next trip I'll go on-line to make reservations to stay at my new favorite B&B in Alajuela. No more searching. I don't think you can do any better. Good value, good ratings, and George is a great host and cook.
