The accommodations were fine generally and the hosts were very helpful and communicative, but this accommodation is not suitable for summer weather. The weather in Porto reached high 90s during my stay and the hosts would not turn on the air conditioning that was set up in the apartment. I reached out in advance concerned about the heat wave, but the hosts said they could not turn on the air conditioning (the unit is equipped with AC, but it was not turned on). After a few hours of being in the room, I started getting very sick from the heat, and had to leave and book another room because my health was at risk. The hosts were very nice, but I am still having trouble processing a refund request. I had to book 2 nights at another hotel in Porto last minute, and should be entitled to a refund.
