So. Many. Mosquitoes.
We spent 6 weeks at this location (late August - early October). We've stayed at dozens of locations over the last two years, and with any location, there are pros and cons.
Pros:
The location within Porto is great.
Lots of light.
Avelina's chocolate cake was delicious, and the hosts were responsive.
Cons:
We spent 6 weeks battling mosquitoes. They were everywhere, and I'm not talking about one or two. Kids were waking up covered in bites and nobody was sleeping. Before my kids went to bed, my husband would have to burn Citronella and then hunt any stray mosquitoes down. He killed hundreds of mosquitoes, and I'm not exaggerating. We tried to keep the windows and doors shut all day long, and it didn't really help. We noticed they seemed to be coming from the restroom - how or why is a mystery to me. If it had been my space, I would have installed nets over the beds. The host suggested we purchase a mosquito lamp, though given the scope of the problem, the apartment should include one in each bedroom.
It was really challenging, and for this reason alone, I can't recommend this location to anyone else.
Also, the shower is really weak. If you want warm water, it dribbles. Good luck getting the shampoo out if you have thick hair.
