Lovelystay
I booked the apartment for the my first 2 nights in Porto and it was a pleasure. After hours of travelling you just want to enter the apartment, jump into the shower and enjoy your ambiente. This cosy little apartment is located 5 - 10 minutes walking into the heart of the city and 5 - 10 minutes walking to the river/ promenade where you can enjoy a nice glass of portwine.
The apartment itself was very clean, super detailed and very well equipped behalf of kitchenette. Also the check-in worked super easy and we could catch up some nice local tips to explore the city. Extra credit: Check-in should´ve been around 3 pm, but when we walked in the Check-in point at 9 am in the morning Sara told us the apartment would already be set for us... VERY NICE ;-).
I´d recommend the lovelystay apartments to everyone and would really enjoy coming back. See you soon guys!
