We stayed for 9 days in Blanes and Alexi & Judith apartment was really great. It was very clean with modern look and nice design touches, all new appliances, including air conditioning. Location of apartment is very convenient as well, you are 3-5 minutes walk from small local beach and maybe 10 mins walk from main beach. We had small issues with flaky Wi-FI connection and occasionally neighbors were pretty noisy at late hours and their dogs were barking loudly as well, but this I guess is out of hosts control.
Alexi & Judith are very nice hosts, they always responded quickly to our questions and made check-in and check-out process very smooth. I definitely can recommend their apartment if you are looking to stay in Blanes.
