I would say that in general the house is quite good, and the location is PERFECT. Helena is very nice and I recommend to book this place because the price-quality relationship is the best. Despite these good feedback I still think some things could improve.
A drawback is that the kitchen is not so well equipped. It requires more cooking tools (pans, pots, good knives etc.) because there is only one of each and really small ones. There is not a dryer for the wet dishes after you wash them (you need to dry them with a cloth) and there were no bags in the trash bin (either in the kitchen or in the toilet). Although Helena told me she would send me further instructions regarding check-in I had to write her 3 messages on the check-in day because I knew nothing.
In the end there was no problem. But I really thing that there are some really easy-to-improve details that would bring this accommodation from quite good to top quality.
