Isabel & Isa's place is nice, very clean and wonderfully decorated. However, there are a few little things that I feel that would have been nice to have or could be improved especially as it is billed as a Plus experience.
The location is OK, a bit out of the city center. You will need to walk up hill on either side to reach public transportation. If you have mobility issues this is not the location for you.
Wifi was slow and sometimes spotty depending on the location. The router is in the living room so it was quite slow in the bedroom. Even in the living room it was not always the best connection. Maybe install a repeater in the hall way and upgrade the speed if possible.
Provided a bath towel and hand towel but that was it. For a Plus experience it would have been nice to have an extra towel or two on hand in case one of the bath towels was not dry. We got caught in a downpour during the day and only had wet towels to use when we came back. Also, not very many places to hang the towels in the bath area.
Could use a bit more hot water as well. If you want to take a shower after someone else has already gone you had to wait around 30 minutes for more hot water. Can be a bit trying when you are rushing out in the morning.
Overall a good place but not sure if I could call it a Plus experience. Everything worked well just small things that we noticed that could be improved. The balcony did have a nice view of the river if it was clear. Again, everything was wonderfully decorated and clean.
